I found this software to be great because it easily repaired my Excel 2016 file in quite a short while.
Was getting "Unsupported data cannot be repaired or removed", so didn't even have an option to use Recovery wizard of excel since the spreadsheet wasn't even opening.
Took approximately 1 minute to repair my 13mb file, IMO that's quick.
No cons to register.
I had encountered "Filename is not valid" error in my highly confidential employee payroll spreadsheet, which I couldn't have afforded to lose so without much delay I downloaded this software and tried it on my file. It showed all the contents of the spreadsheet in the preview.
I immediately bought the software, and it completely repaired my spreadsheet.
I honestly do not have words to express my gratitude.
