Hi,
With Excel 2008 on Mac I can open a .xls file without issues.
When writing the same file to .xlsx I see the above error message.
Additionally it says ‘The file might have been damaged or modified from its original format.’.
The way I write the file is like this:
workbook.save(outputStream, FileFormatType.EXCEL2000);
or
workbook.save(outputStream, FileFormatType.EXCEL2007);
I attached the files.
