How can I determine the original creator of a spreadsheet?

[Guest]

I received an Excel spreadsheet attached to an e-mail. Is there a way to
determine whether the individual who sent me the spreadsheet is the original
creator, or if someone else created it for her and she forwarded it to me?

Thanks is advance for any information.

It's worth looking at File/ Properties/ Summary from within Excel. That
might have been changed since the sheet was originally created, but it's
worth having a look.

Thank you for your response. I did as you suggested, but I think that the
original sheet may have been changed and that's why I had asked the question.
It could be that there is no way to tell. I just don't know that for sure.
