I'm having the same problem as the OP and have already tried the method
included in that FAQ.

Digging around some more on the internet, I found that someone suggested to
"always save in the latest and greatest file format". Since I'm using
Excel2007 in an office where most users are still using 2003, I have been
saving in the .xls format. I gave it a shot in the .xlsx format and the file
size was reduced from 28MB to 6MB. For a workbook that really doesn't have
that much data, it's still too big, but its a significant improvement.

I'm wondering though if there are any other workarounds aside from saving in
that file format that isn't compatible with a large part of my office.

I have a large Excel file with maybe 9 worksheets. It is 4,361KB and there
is no way it should be that large. I have systematically deleted worksheets
and the file remains the same size. Is there some trick to getting Excel to
reduce the file size? Any thoughts appreciated. Thank you.
