Hello,

I've tried using the PEAR Worksheet package to create .XLS files but
the spreadsheet format corresponds to Excel 5 format.

I would like to be able to create an Excel file that adheres to the
Microsoft Office Excel Workbook format. Is there any PHP library, or
any other language's library, that would allow me to do so ?

Thanks.
