I am currently working on an issue with Excel 2007. I open a file that was
previously made with Excel 2003 and was only 1.7 MB but when I opened the
file in Excel 2007 and clicked save the files size jumped to 2.43 MB. Now
that I have done that when I try to open the file it takes about 10 minutes
to open, if it opens at all. I have tried going into each sheet and deleting
the empty cells as mentioned in other threads and it did reduce the size a
little. It went from 2.43 MB to 2.26 MB. Is there any other way to reduce the
file size? Saving them as .xslx files does reduce the size by half, but I
cannot save the files as .xslx because some users are still on Office XP and
2003. The network also blocks them from downloading anything from the
internet such as the compatibility update tp read the .xlsx files.
