Hi Steph,
This question must be almost identical to to one that someone posted in June.,
because right after I wrote it someone asked such a question.

Save each worksheet separately to multiple workbooks (#MakeMultipleXLSfromWB)
Saveas, Save each worksheet as a separate workbook
http://www.mvps.org/dmcritchie/excel/saveas.htm
and them look in the generated subdirectory of your c:\temp\D....
to see the file sizes.

Hi
don't think such an utility exists but you may check the used range for
each sheet (and correct it). See:

Hi all. Does anyone have a utility or know how to determine how much
memory each sheet in a workbook is responsible for? I have a
workbook that is 21MB in size. I'd like to reduce the size, but it
would be easier if i knew which sheets in particular were the memory
hogs. Thanks!
