I am using 2007 version of Excel to design a spreadsheet at work. It is
capable of over handling over 16,000 columns.

The users of my spreadsheat have 2002 version of Excel. If the
update/upgrade via downloading the compatibility software, will they then be
able to also handle the 16,000+ columns?

My design is utilizing 3000 columns per worksheet with over 100 worksheets
in the workbook.

Thanks,
Les
