I opened an Excel file with a password supplied by another user and want to remove the password encryption. When I go to File > Info > Protect Workbook > Encrypt with Password, there is nothing to delete so how do I remove the password encryption?
So you can't open the file at all unless you supply a password?
Or can you open it but the sheets are hidden / locked unless you supply a password?
Is it a .xlsm file?
What version of Excel are you using?
