By any chance, do you have Pivot Tables in your file?

Hi,
does anyone know how I can reduce the file size of an excel workbook? I
have been working with this file for a year- it has always been under
5MB -
all of a sudden the last 2 or 3 times I have worked on it and saved it -
it
has gone to 21MB (and I can't figure out why) !! Now I can't email it
because
it is too big.

Thanks for any help
