' syntax to replace single quote mark

' syntax to replace single quote mark

I have an entire spreadsheet that uses a single quote mark about 1000 times.  When I opened the document this morning, all the single quote marks had been replaced by ' in the spreadsheet.  The formula bar reflects the correct single quote and does not reflect the ' syntax.  It's only this way in the body of the spreadsheet.

I'm hoping for a simple find all / replace all command that I might be able to use.  Not to mention that there seems to be a bug - i won't be using the single quote any longer on Zoho :(

Anyway that I can get rid of this syntax?  I've tried copying/pasting to another Excel spreadsheet but it only copies unicode text (and didn't capture the entire spreadsheet anyway).  Help!!
