Other languages: `https://www.chilkatsoft.com/ai-docs/v/11.7.0//classes/Csv.md`. > Language-wide rules (install, unlock, error model, strings/bytes): `https://www.chilkatsoft.com/ai-docs/v/11.7.0/xojo/guide.md`. ## Purpose **Read, edit, sort, and write CSV or delimiter-separated data in memory.** `Chilkat.Csv` is a practical in-memory table class for working with CSV and other delimiter-separated text formats. It can load CSV data from files or strings, access cells by row/column index or column name, manage header rows, insert and delete rows or columns, sort records, search for matching rows, and write the result back using configurable delimiters, quoting rules, character encodings, and line endings. **In-memory CSV table** Load CSV data, modify cells, add rows, delete rows or columns, and write the updated table back to a file or string. **Header and named columns** Use a header row to access fields by column name instead of only by numeric column index. **Cell and row operations** Read and update individual cells, insert columns, remove data, find matching rows, and sort the table as needed. **Delimiter control** Work with comma-separated data or other delimiter-separated formats by configuring the delimiter character. **Quoting and output formatting** Control quoted fields, forced quoting, output line endings, explicit character encodings, and UTF-8 BOM emission. **Excel worksheet loading** Load worksheet data from an opened `.xlsx` ZIP container when CSV-style access to spreadsheet content is needed. **Common pattern:** Load CSV data, specify whether the first row is a header, access or modify cells by index or column name, perform any row, column, search, or sort operations, then save the table using the delimiter, charset, quoting, BOM, and line-ending settings required by the target system. For an extended overview, see [Csv Class Overview](https://www.chilkatsoft.com/csv_class_overview.asp). ## Object creation, unlocking and error handling **Object Creation** ```xojo Dim csv As New Chilkat.Csv ``` Call `Global.UnlockBundle` once at the start of the program, before using this or any other Chilkat class. Any string unlocks a fully functional 30-day trial; a purchased unlock code is used in production. See `guide.md` for the exact code in Xojo. How failure is reported depends on the method's return type and is stated in the note under each method below. In every case the diagnostic text is in the `LastErrorText` property of the object whose method was called. ## Members common to every Chilkat class Documented once per language in `common-members.md`; listed here so this page is self-contained. | Property | Signature | Access | Meaning | |---|---|---|---| | `DebugLogFilePath` | `DebugLogFilePath As String` | read/write | If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. | | `LastErrorHtml` | `LastErrorHtml As String (read-only)` | read-only | Provides HTML-formatted information about the last called method or property. | | `LastErrorText` | `LastErrorText As String (read-only)` | read-only | Provides plain text information about the last called method or property. | | `LastErrorXml` | `LastErrorXml As String (read-only)` | read-only | Provides XML-formatted information about the last called method or property. | | `LastMethodSuccess` | `LastMethodSuccess As Boolean` | read/write | Indicates the success or failure of the most recent method call: `True` means success, `False` means failure. | | `VerboseLogging` | `VerboseLogging As Boolean` | read/write | If set to `True`, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. | | `Version` | `Version As String (read-only)` | read-only | Version of the component/library, such as "10.1.0" | ## Member index | Member | Kind | Signature | |---|---|---| | `AutoTrim` | property, read/write | `AutoTrim As Boolean` | | `Crlf` | property, read/write | `Crlf As Boolean` | | `Delimiter` | property, read/write | `Delimiter As String` | | `EnableQuotes` | property, read/write | `EnableQuotes As Boolean` | | `EscapeBackslash` | property, read/write | `EscapeBackslash As Boolean` | | `HasColumnNames` | property, read/write | `HasColumnNames As Boolean` | | `NumColumns` | property, read-only | `NumColumns As Int32 (read-only)` | | `NumRows` | property, read-only | `NumRows As Int32 (read-only)` | | `UncommonOptions` | property, read/write | `UncommonOptions As String` | | `XlsxDateFormat` | property, read/write | `XlsxDateFormat As String` | | `DeleteColumn` | method | `Function DeleteColumn(index As Int32) As Boolean` | | `DeleteColumnByName` | method | `Function DeleteColumnByName(columnName As String) As Boolean` | | `DeleteRow` | method | `Function DeleteRow(index As Int32) As Boolean` | | `GetCell` | method | `Function GetCell(row As Int32, col As Int32) As String` | | `GetCellByName` | method | `Function GetCellByName(rowIndex As Int32, columnName As String) As String` | | `GetColumnName` | method | `Function GetColumnName(index As Int32) As String` | | `GetIndex` | method | `Function GetIndex(columnName As String) As Int32` | | `GetNumCols` | method | `Function GetNumCols(row As Int32) As Int32` | | `InsertColumn` | method | `Function InsertColumn(index As Int32) As Boolean` | | `LoadFile` | method | `Function LoadFile(path As String) As Boolean` | | `LoadFile2` | method | `Function LoadFile2(filename As String, charset As String) As Boolean` | | `LoadFromString` | method | `Function LoadFromString(csvData As String) As Boolean` | | `RowMatches` | method | `Function RowMatches(rowIndex As Int32, matchPattern As String, caseSensitive As Boolean) As Boolean` | | `SaveFile` | method | `Function SaveFile(path As String) As Boolean` | | `SaveFile2` | method | `Function SaveFile2(filename As String, charset As String) As Boolean` | | `SaveToSb` | method | `Function SaveToSb(sb As Chilkat.StringBuilder) As Boolean` | | `SaveToString` | method | `Function SaveToString() As String` | | `SetCell` | method | `Function SetCell(row As Int32, col As Int32, content As String) As Boolean` | | `SetCellByName` | method | `Function SetCellByName(rowIndex As Int32, columnName As String, contentStr As String) As Boolean` | | `SetColumnName` | method | `Function SetColumnName(index As Int32, columnName As String) As Boolean` | | `SortByColumn` | method | `Function SortByColumn(columnName As String, ascending As Boolean, caseSensitive As Boolean) As Boolean` | | `SortByColumnIndex` | method | `Function SortByColumnIndex(index As Int32, ascending As Boolean, caseSensitive As Boolean) As Boolean` | | `XlsxGetSheets` | method | `Function XlsxGetSheets(xlsx As Chilkat.Zip, sheetNames As Chilkat.StringTable) As Boolean` | | `XlsxLoadSheet` | method | `Function XlsxLoadSheet(zip As Chilkat.Zip, sheetName As String) As Boolean` | ## Properties ### Csv.AutoTrim `Chilkat 11.7.0 · xojo · Csv · AutoTrim · property · read/write` ```xojo AutoTrim As Boolean ``` Controls whether leading and trailing whitespace is removed from values returned by `GetCell` and `GetCellByName`. - When `True`, surrounding whitespace such as spaces and tabs is removed from returned cell values. - When `False`, returned cell values are not trimmed. This is the default. This property does not modify the cell contents stored in the CSV and does not change the text written by the save methods. It also does not trim the names returned by `GetColumnName`. ### Csv.Crlf `Chilkat 11.7.0 · xojo · Csv · Crlf · property · read/write` ```xojo Crlf As Boolean ``` Controls the line endings used by `SaveFile`, `SaveFile2`, `SaveToString`, and `SaveToSb`. - When `True`, records are terminated with CRLF. This is the default. - When `False`, records are terminated with LF. The original line-ending style of loaded data is not preserved. The selected line ending is used for all output records, including the final record. ### Csv.Delimiter `Chilkat 11.7.0 · xojo · Csv · Delimiter · property · read/write` ```xojo Delimiter As String ``` Specifies the single character used to separate fields within each CSV record. The default value is a comma (`,`). Although this property has a string type, only the first character of a non-empty value is used. Assigning an empty string does not clear or reset the current delimiter. If the delimiter has not been explicitly set, Chilkat detects it while loading the first CSV data and updates this property with the detected character. The detection may examine more than the first record. Once selected or detected, the delimiter remains in effect for subsequent loads performed by the same object. To load data that uses a different delimiter, explicitly set this property before loading or use a new `Csv` object. A semicolon (`;`) is commonly used in locales where a comma is used as the decimal separator. **Creating a new CSV:** Set this property before adding rows or columns when a delimiter other than comma is required. **Vertical-bar delimiter:** If this property is explicitly set to `|`, and `EnableQuotes` has not been explicitly set, `EnableQuotes` defaults to `False`. ### Csv.EnableQuotes `Chilkat 11.7.0 · xojo · Csv · EnableQuotes · property · read/write · since 9.5.0.71` ```xojo EnableQuotes As Boolean ``` Controls whether double quotation marks have their standard CSV meaning when reading and writing data. The default value is `True`. When `True`, a quoted field is treated as one field even when it contains the delimiter, CR, or LF. A double quotation mark inside a quoted field is represented by two consecutive double quotation marks. Fields created by the application are quoted automatically when required. Chilkat retains whether a field loaded from CSV text was quoted, so quotation marks that were not strictly required may remain when the CSV is saved again. When `False`, quotation marks are ordinary characters and do not protect delimiters or line endings. Do not disable quoting when field values can contain the delimiter, quotation marks, CR, or LF, because such values cannot be represented or round-tripped reliably as ordinary delimited text. ### Csv.EscapeBackslash `Chilkat 11.7.0 · xojo · Csv · EscapeBackslash · property · read/write · since 9.5.0.44` ```xojo EscapeBackslash As Boolean ``` Controls whether a backslash causes the following character to be treated literally while parsing CSV data. The default value is `False`. When `True`, examples include: - `\,` represents a literal delimiter character. - `\\` represents one backslash. - `\"` represents a literal double quotation mark. This is not C-style escape decoding. For example, `\n`, `\r`, and `\t` produce the literal characters `n`, `r`, and `t`; they do not produce a line feed, carriage return, or tab. Normal CSV quoting is still used when output fields contain delimiters or line endings. ### Csv.HasColumnNames `Chilkat 11.7.0 · xojo · Csv · HasColumnNames · property · read/write` ```xojo HasColumnNames As Boolean ``` Indicates whether the first record is a column-name row rather than a data row. The default value is `False`. Set this property to `True` **before** loading CSV data when the first record contains column names. Chilkat then stores the first record as the column names and excludes it from `NumRows` and zero-based data-row indexing. Changing this property to `True` after data has already been loaded does not reinterpret the first data row as column names. Calling `SetColumnName` automatically changes this property to `True`. Methods that address a column by name require this property to be `True` and require the requested name to exist. ### Csv.NumColumns `Chilkat 11.7.0 · xojo · Csv · NumColumns · property · read-only` ```xojo NumColumns As Int32 (read-only) ``` The number of columns in the first row of the CSV. When `HasColumnNames` is `True`, this is the number of column names in the header row. CSV rows may contain different numbers of fields. Therefore, this property is not necessarily the maximum number of columns found in any row. Use `GetNumCols` to obtain the number of columns in a particular data row. ### Csv.NumRows `Chilkat 11.7.0 · xojo · Csv · NumRows · property · read-only` ```xojo NumRows As Int32 (read-only) ``` The number of data rows in the CSV. - When `HasColumnNames` is `True`, the column-name row is not included. - Interior blank rows are included. - Empty or whitespace-only rows following the last non-empty row are not included. ### Csv.UncommonOptions `Chilkat 11.7.0 · xojo · Csv · UncommonOptions · property · read/write · since 9.5.0.88` ```xojo UncommonOptions As String ``` Provides optional keywords for uncommon CSV-processing requirements. The default value is an empty string, and this property should normally remain empty. To enable more than one option, use a comma-separated list. The following keywords are defined: - `QuotedCells` (v9.5.0.96) — Encloses every data cell in double quotation marks when writing the CSV. - `QuotedColumnNames` (v9.5.0.96) — Encloses every column name in double quotation marks when writing the CSV. - `EMIT_BOM` (v9.5.0.93) — Writes a UTF-8 byte order mark when saving a UTF-8 encoded CSV file. ### Csv.XlsxDateFormat `Chilkat 11.7.0 · xojo · Csv · XlsxDateFormat · property · read/write · since 11.3.0` ```xojo XlsxDateFormat As String ``` Specifies the date format used when converting Excel date cells from an `.xlsx` worksheet to CSV text. The default value is `mm-dd-yy`. Other formats include `d/m/yyyy`, `m/d/yyyy`, and similar Excel-style date-format patterns. ## Methods ### Csv.DeleteColumn `Chilkat 11.7.0 · xojo · Csv · DeleteColumn · method` ```xojo Function DeleteColumn(index As Int32) As Boolean ``` Deletes the column at zero-based index `index`. The deletion is applied to the column-name row, when present, and to each data row that contains that column. `index` must not be negative. For predictable deletion, `index` should be less than `NumColumns`. Returns True for success, False for failure. ### Csv.DeleteColumnByName `Chilkat 11.7.0 · xojo · Csv · DeleteColumnByName · method` ```xojo Function DeleteColumnByName(columnName As String) As Boolean ``` Deletes the column named by `columnName`. This method requires `HasColumnNames` to be `True`. Column-name matching is case-sensitive. Surrounding whitespace in a loaded column name is not part of its lookup name. Column names should be unique to avoid ambiguous lookup and deletion behavior. Returns True for success, False for failure. ### Csv.DeleteRow `Chilkat 11.7.0 · xojo · Csv · DeleteRow · method` ```xojo Function DeleteRow(index As Int32) As Boolean ``` Deletes the data row at zero-based index `index`. The first data row is at index `0`, regardless of whether a column-name row exists. `index` must be between `0` and `NumRows - 1`. Returns True for success, False for failure. ### Csv.GetCell `Chilkat 11.7.0 · xojo · Csv · GetCell · method` ```xojo Function GetCell(row As Int32, col As Int32) As String ``` Returns the contents of the cell at data row `row` and column `col`. Row and column indexes are zero-based. The upper-left data cell is at row `0`, column `0`. When `HasColumnNames` is `True`, the header row is not included in the row index. - If `row` is negative or beyond the available data rows, `Nil` is returned and `LastMethodSuccess` is `False`. - If `col` is negative, `Nil` is returned and `LastMethodSuccess` is `False`. - If `row` is valid but `col` is beyond the number of fields in that row, an empty string is returned and `LastMethodSuccess` is `True`. When `AutoTrim` is `True`, surrounding whitespace is removed from the returned value without changing the stored cell content. Returns `Nil` on failure ### Csv.GetCellByName `Chilkat 11.7.0 · xojo · Csv · GetCellByName · method` ```xojo Function GetCellByName(rowIndex As Int32, columnName As String) As String ``` Returns the contents of the cell at data row `rowIndex` in the column named by `columnName`. Row indexing begins at `0` and excludes the header row. This method requires `HasColumnNames` to be `True`. Column-name matching is case-sensitive. Surrounding whitespace is removed from column names for lookup purposes, so `columnName` should contain the trimmed name. If duplicate lookup names exist, the last matching column is used. If the row or column name is invalid, `Nil` is returned and `LastMethodSuccess` is `False`. When `AutoTrim` is `True`, surrounding whitespace is removed from the returned cell value. Returns `Nil` on failure ### Csv.GetColumnName `Chilkat 11.7.0 · xojo · Csv · GetColumnName · method` ```xojo Function GetColumnName(index As Int32) As String ``` Returns the original, untrimmed name of the column at zero-based index `index`. The first column is at index `0`. Returns `Nil` on failure ### Csv.GetIndex `Chilkat 11.7.0 · xojo · Csv · GetIndex · method` ```xojo Function GetIndex(columnName As String) As Int32 ``` Returns the zero-based index of the column named by `columnName`, or `-1` if no matching column exists. This method requires `HasColumnNames` to be `True`. Matching is case-sensitive. Surrounding whitespace is removed from loaded column names for lookup purposes, so `columnName` should contain the trimmed name. If duplicate lookup names exist, the index of the last matching column is returned. ### Csv.GetNumCols `Chilkat 11.7.0 · xojo · Csv · GetNumCols · method` ```xojo Function GetNumCols(row As Int32) As Int32 ``` Returns the number of fields in the data row at zero-based index `row`. This is useful for CSV data containing rows of different lengths. Returns `0` if `row` is negative or beyond the available data rows. ### Csv.InsertColumn `Chilkat 11.7.0 · xojo · Csv · InsertColumn · method · since 9.5.0.89` ```xojo Function InsertColumn(index As Int32) As Boolean ``` Inserts one empty field into each existing row and, when present, into the column-name row. `index` is a zero-based insertion position. - If `index` is within a row, the empty field is inserted before that position. - If `index` is at or beyond the end of a row, one empty field is appended to that row. - Rows are not padded to a common width, so ragged rows remain ragged. - Calling this method on an object with no rows and no column-name row has no effect. `index` must not be negative. Returns True for success, False for failure. ### Csv.LoadFile `Chilkat 11.7.0 · xojo · Csv · LoadFile · method` ```xojo Function LoadFile(path As String) As Boolean ``` Clears the current contents and loads CSV data from the file specified by `path`. Set `HasColumnNames`, `Delimiter`, `EnableQuotes`, and other parsing options before calling this method. On Windows, the file is decoded using the current Windows ANSI code page. Use `LoadFile2` when the character encoding must be specified explicitly. The existing CSV contents are cleared before the file is opened. Therefore, a failure such as a missing file does not preserve the previously loaded data. Returns True for success, False for failure. ### Csv.LoadFile2 `Chilkat 11.7.0 · xojo · Csv · LoadFile2 · method` ```xojo Function LoadFile2(filename As String, charset As String) As Boolean ``` Clears the current contents and loads CSV data from the file specified by `filename`. `charset` specifies the character encoding used by the file. Set `HasColumnNames`, `Delimiter`, `EnableQuotes`, and other parsing options before calling this method. See [Supported Charsets](https://www.chilkatsoft.com/charsets_supported_by_chilkat.asp) for the encoding names recognized by Chilkat. Returns True for success, False for failure. ### Csv.LoadFromString `Chilkat 11.7.0 · xojo · Csv · LoadFromString · method` ```xojo Function LoadFromString(csvData As String) As Boolean ``` Clears the current contents and loads the CSV text contained in `csvData`. Set `HasColumnNames`, `Delimiter`, `EnableQuotes`, and other parsing options before calling this method. Passing an empty string successfully clears the CSV. The parser is permissive; for example, an unterminated quoted field extends through the end of `csvData` rather than necessarily causing the load to fail. Returns True for success, False for failure. ### Csv.RowMatches `Chilkat 11.7.0 · xojo · Csv · RowMatches · method` ```xojo Function RowMatches(rowIndex As Int32, matchPattern As String, caseSensitive As Boolean) As Boolean ``` Compares the complete data row at zero-based index `rowIndex` with the wildcard pattern in `matchPattern`. The row is compared as one delimited record using the current `Delimiter`; the pattern may therefore include or span field separators. - The asterisk character (`*`) may appear any number of times and matches zero or more characters. - When `caseSensitive` is `True`, matching is case-sensitive. - When `caseSensitive` is `False`, matching is case-insensitive. - `AutoTrim` does not alter the row used for matching. Returns `True` when the row matches `matchPattern`. Returns `False` when it does not match or when `rowIndex` is outside the available data rows. ### Csv.SaveFile `Chilkat 11.7.0 · xojo · Csv · SaveFile · method` ```xojo Function SaveFile(path As String) As Boolean ``` Writes the entire CSV to the file specified by `path`. On Windows, the text is encoded using the current Windows ANSI code page. Use `SaveFile2` when the output encoding must be specified explicitly. Record endings are controlled by `Crlf`, and the final record is also followed by the selected line ending. Returns True for success, False for failure. ### Csv.SaveFile2 `Chilkat 11.7.0 · xojo · Csv · SaveFile2 · method` ```xojo Function SaveFile2(filename As String, charset As String) As Boolean ``` Writes the entire CSV to the file specified by `filename`. `charset` specifies the output character encoding, and Chilkat converts the CSV text to that encoding while saving. Record endings are controlled by `Crlf`, and the final record is also followed by the selected line ending. See [Supported Charsets](https://www.chilkatsoft.com/charsets_supported_by_chilkat.asp) for the encoding names recognized by Chilkat. Returns True for success, False for failure. ### Csv.SaveToSb `Chilkat 11.7.0 · xojo · Csv · SaveToSb · method · since 9.5.0.93` ```xojo Function SaveToSb(sb As Chilkat.StringBuilder) As Boolean ``` Clears `sb` and writes the entire CSV document into it. Record endings are controlled by `Crlf`. `sb` contains a line ending after the final record. Returns True for success, False for failure. ### Csv.SaveToString `Chilkat 11.7.0 · xojo · Csv · SaveToString · method` ```xojo Function SaveToString() As String ``` Returns the entire CSV document as a string. Record endings are controlled by `Crlf`. The returned string includes a line ending after the final record. The line-ending style originally loaded into the object is not preserved. Returns `Nil` on failure ### Csv.SetCell `Chilkat 11.7.0 · xojo · Csv · SetCell · method` ```xojo Function SetCell(row As Int32, col As Int32, content As String) As Boolean ``` Sets the cell at zero-based data row `row` and column `col` to `content`. The CSV grows as needed. If `row` is beyond the current last row, intervening rows are created as empty rows. Within the target row, intervening columns are created as empty cells. Other rows are not padded, so the resulting CSV may contain rows with different numbers of fields. Passing `NumRows` as `row` appends a new data row. `content` may contain delimiters, quotation marks, CR, and LF when `EnableQuotes` is `True`; Chilkat applies the necessary CSV quoting when the data is saved. `row` and `col` must not be negative. Returns True for success, False for failure. ### Csv.SetCellByName `Chilkat 11.7.0 · xojo · Csv · SetCellByName · method` ```xojo Function SetCellByName(rowIndex As Int32, columnName As String, contentStr As String) As Boolean ``` Sets the cell at zero-based data row `rowIndex` in the column named by `columnName` to `contentStr`. This method requires `HasColumnNames` to be `True` and requires `columnName` to match an existing column name. Matching is case-sensitive and uses the trimmed lookup form of the stored column name. A missing column is not created. The data-row collection grows as needed. `contentStr` may contain delimiters, quotation marks, CR, and LF when `EnableQuotes` is `True`. Returns True for success, False for failure. ### Csv.SetColumnName `Chilkat 11.7.0 · xojo · Csv · SetColumnName · method` ```xojo Function SetColumnName(index As Int32, columnName As String) As Boolean ``` Sets the name of the column at zero-based index `index` to `columnName`. The first column is at index `0`. Calling this method automatically sets `HasColumnNames` to `True`. It can therefore be used on an empty object to create the column-name row. `index` must not be negative. For reliable name-based access, use unique column names without surrounding whitespace. Returns True for success, False for failure. ### Csv.SortByColumn `Chilkat 11.7.0 · xojo · Csv · SortByColumn · method` ```xojo Function SortByColumn(columnName As String, ascending As Boolean, caseSensitive As Boolean) As Boolean ``` Sorts the data rows using the values in the column named by `columnName`. The column-name row is not moved. - When `ascending` is `True`, rows are sorted in ascending order. - When `ascending` is `False`, rows are sorted in descending order. - When `caseSensitive` is `True`, comparisons are case-sensitive. - When `caseSensitive` is `False`, comparisons are case-insensitive. Values are compared as strings, not as numbers or dates. For example, ascending order places `10` before `2`. Empty or missing sort cells appear first in ascending order and last in descending order. The sort is not stable, so rows having equal sort values may change relative order. This method requires `HasColumnNames` to be `True` and `columnName` to name an existing column. Returns True for success, False for failure. ### Csv.SortByColumnIndex `Chilkat 11.7.0 · xojo · Csv · SortByColumnIndex · method · since 9.5.0.83` ```xojo Function SortByColumnIndex(index As Int32, ascending As Boolean, caseSensitive As Boolean) As Boolean ``` Sorts the data rows using the values in the column at zero-based index `index`. The column-name row, when present, is not moved. - When `ascending` is `True`, rows are sorted in ascending order. - When `ascending` is `False`, rows are sorted in descending order. - When `caseSensitive` is `True`, comparisons are case-sensitive. - When `caseSensitive` is `False`, comparisons are case-insensitive. Values are compared as strings, not as numbers or dates. Empty and missing sort cells are treated as empty strings. They appear first in ascending order and last in descending order. The sort is not stable, so rows having equal sort values may change relative order. Returns True for success, False for failure. ### Csv.XlsxGetSheets `Chilkat 11.7.0 · xojo · Csv · XlsxGetSheets · method · since 11.3.0` ```xojo Function XlsxGetSheets(xlsx As Chilkat.Zip, sheetNames As Chilkat.StringTable) As Boolean ``` Gets the worksheet names contained in an Excel `.xlsx` workbook. - `xlsx` is a `Zip` object containing the already-opened `.xlsx` file. - `sheetNames` receives the worksheet names. Returns True for success, False for failure. ### Csv.XlsxLoadSheet `Chilkat 11.7.0 · xojo · Csv · XlsxLoadSheet · method · since 11.3.0` ```xojo Function XlsxLoadSheet(zip As Chilkat.Zip, sheetName As String) As Boolean ``` Loads a worksheet from an Excel `.xlsx` workbook into this CSV object. - `zip` is a `Zip` object containing the already-opened `.xlsx` file. - `sheetName` is the worksheet name. - Pass an empty string in `sheetName` to load the workbook's default worksheet. The `XlsxDateFormat` property controls the text format used for Excel date cells. Returns True for success, False for failure. ## Related classes [`StringBuilder`](https://www.chilkatsoft.com/ai-docs/v/11.7.0/xojo/classes/StringBuilder.md), [`StringTable`](https://www.chilkatsoft.com/ai-docs/v/11.7.0/xojo/classes/StringTable.md), [`Zip`](https://www.chilkatsoft.com/ai-docs/v/11.7.0/xojo/classes/Zip.md)
