LibreOffice just crashed while I was editing an unprotected spreadsheet.
Now the spreadsheet is protected and I can’t modify it.
Obviously I didn’t assign a password so I can’t just unprotect it in the normal way.
This is a matter of file corruption due to a LibreOffice bug that has apparently been around for years.
How do I fix it?
Sorry but I have to supply a file to my office very soon and I am completely stuck.
Very unpleasant user experience.
