xlsNbColumn (Function)

In french: xlsNbColonne

Returns the number of columns found in a worksheet of an XLS file. The result depends on the opening mode of XLS file:

In multi-sheet mode, the number of columns is calculated for the worksheet selected by xlsCurrentWorksheet.
In compatible mode, the number of columns is always calculated for the first worksheet of the workbook.

This function assumes that the XLS file has a database structure, which means that each row corresponds to a fixed number of columns.

Remark: The number of columns in an XLS file can be found if:

The XLS file exists.
The XLS file is opened.
