- Using the XLS functions in read/write
- The XLS file cannot be opened
xlsOpen (Function) In french: xlsOuvre Opens an Excel file. The supported formats are: - XLS and XLSX (Excel workbook),
- XLSM (Excel macro-enabled workbook),
- XLTX (Excel template),
- XLTM (Excel macro-enabled template),
 New in version 2025CSV (csv file).
Note: To create an Excel file without using an initial file, simply create a variable of type xlsDocument (in this case, xlsOpen has no effect). New in version 2025 doc is xlsDocument
doc = xlsOpen(fExeDir() + ["\"] + "gpac.xls")
IF ErrorOccurred() THEN
Error(ErrorInfo())
RETURN
END
Info("Content of [1,1] cell:", doc[1,1])
xlsClose(doc)
Syntax
<Result> = xlsOpen(<Path of XLS file> [, <Opening mode> [, <Password>]])
<Result>: xlsDocument variable Name of the xlsDocument variable corresponding to the XLS file. This variable can be used by all the XLS functions. Using this type of variable allows you to modify the XLS documents.
 Warning
Result compatible with version 12. For compatibility reasons, this variable can be converted to an integer corresponding to the specified XLS file ID. This ID can be used in all XLS functions that support the file ID. Using this syntax with an ID only allows you to read XLS documents. You will not be able to make any changes.
<Path of XLS file>: Character string Full or relative path of the file to be opened (up to 260 characters). The supported formats are: - XLS and XLSX (Excel workbook),
- XLSM (Excel macro-enabled workbook),
- XLTX (Excel template),
- XLTM (Excel macro-enabled template),
New in version 2025CSV (csv file).
<Opening mode>: Optional integer constant Indicates the opening mode of XLS file.
By default: - the Excel file is opened in read-only mode. You can write to the Excel file with another application.
- the Excel file uses the multi-sheet management mode for XLS files.
| | | xlsCompatible | Used to open the Excel file in mode compatible with version 10. In this mode: - A single workbook sheet is supported.
- Unicode is not supported.
- The groups of strings are not supported.
- Some functions (xlsData or xlsNbRow for example) may return inconsistent results.
Warning
From version 11, this constant is available for backward compatibility.
| | xlsWrite | Opens the Excel file in "Read/Write" mode. The XLS file is opened and locked until it is closed.
Note: Any changes made in the XLS file can only be taken into account if you use a variable of type xlsDocument. |
<Password>: Optional character string Password to open the XLS file to use. Remarks Using the XLS functions in read/write To handle the XLS files in read/write, you must use an xlsDocument variable. This type of variable can also be used to handle the files specific to Office 2007 (.xlsx files) in read/write. The use of the file identifier is kept for backward compatibility with version 12. The XLS documents (including the ".xlsx" files specific to Office 2007) handled with this identifier cannot be modified (even if the xlsWrite constant is specified). Example using the syntax kept for backward compatibility: XLSFileID is int
XLSFileID = xlsOpen(CompleteDir(fExeDir()) + "GPACS.XLS")
IF ErrorOccurred = False THEN
Info("The XLS file was opened")
xlsClose(XLSFileID)
ELSE
Info(ErrorInfo())
END
END
The XLS file cannot be opened The possible error cases are as follows: - The specified XLS file was not found.
- The specified XLS file does not exist.
- The specified XLS file cannot be opened.
- The specified XLS file is invalid.
- Insufficient memory to open the XLS file.
- The version of Excel used is unknown or too old (the XLS functions cannot read the files in Excel version 2 or earlier).
To get more details on the error, use xlsMsgError (if your are using version-12-compatible syntax) or ErrorInfo with the errMessage constant.
