I have important MS Excel file data and unfortunately got damage due to virus attacks, so my crucial Excel sheet got lost, How to repair corrupt MS Excel (XLS and XLSX) Files. If have any solution please assist me.
Once you're sure you are completely clear of the threats, download https://onlinefilerepair.com/en/excel-repair-online.html and install it. It's a free utility and works well but if the sheet was open when the attack hit, you may not be able to reconstitute it. If you search your system for files with names starting with a $ symbol, you might find the temporary file Excel creates as soon as you open the original. That could be recovered as the files before you started working on it the last time.
