Don't know of a way to determine original excel version.

However, if you go to File - Properties, you can find the create date.

And if you never access the file with a newer version of Excel, you
typically get a message indicating the Excel version that was last used to
edit the document...

Hello All,

Is there any way to find which version of Excel was used to create a file.

My files vary from 1997 to present.

Many thanks
