XL: Error Message: Too Many Different Cell Formats
http://support.microsoft.com/default.aspx?scid=213904

Some people have said that they can open workbooks in OpenOffice.org and fix the
formatting, resave and then excel can use it.

http://openoffice.org
is where you''d go to download the free office suite.
