I have some old backups of Excel 2003 documents and would like to verify
current copies against them! Therefore i am using the MD5 hashes for
comparing. But obviously this is failing because just opening and closing a
file causes the MD5 to change making the whole exercise useless! I do not
have any issues with any other type of Office 2003 documents.

I like to routinely check my documents against backups by comparing MD5

However, I find this impossible with Excel files because the MD5 value
changes just from opening and closing documents. I do not have this problem
with Word documents or any other type of file.
Could someone advise if there is an Excel setting that is causing this? If
so, do I need to use another file integrity checking method? What?
