I am trying to open an Excel file containing 20 spread

This answer was rated:

I am trying to open an Excel file containing 20 spread sheets, a file I hv used on many occasions, however I am now told that it is in a different format than specified by the file extension, if I try to verify the file, it condenses my 20 sheets into one which I can't open.
How can I retrieve this data? and how can I prevent it from happening again, this is the third such file this has happen to.

Hello Ian,

What version of Excel are you using?

What version was the file created in?

Did you recently upgrade Excel or MS Office?

Can you attach the file here using the paperclip icon so I may view it?
