Excel 2007 can very easily work with files created in Excel 2003 and
earlier. Therefore, you can take files from your work copy of Excel 2003 and
work on them from home using Excel 2007. The reverse is not automatically
true. The internal file format was changed in Excel 2007, and Excel 2003
cannot read 2007 files (there is a compatibility package to allow this). If
you create a file in Excel 2007, you will need to save the file in the 2003
format if you want to work on it from 2003 at work. When you use Excel 2007
in 2003 compatibility mode, the newly added features of Excel 2007 will not
be available.

Unless you really need Excel 2007, you might find it considerably less
expensive to purchase a valid copy of Excel/Office 2003.

I am hoping someone can help me. I am not very savvy with computers. I
have
Excel 2003 at work and want to be able to work on things at home. If I
buy
Excel 2007 can I email myself spreadsheets at home and work on them and
then
send them back to myself at work and continue working on them?

Thank you!
