How Can I Recover an Unknown Password to Unlock an Excel File?

I have an Excel workbook that is protected with an unknown password, and I am unable to open the file. The password was set earlier, but it is no longer available. Since the workbook contains important information, I need a solution that can recover the password without damaging the original Excel file.

I have already tried possible password combinations, but none of them worked. I understand that Excel uses strong encryption for the Password to Open protection, and simple methods like removing sheet protection or editing XML files may not work in this situation.

For recovering an unknown Excel password, I found that SysTools Excel Password Recovery can be useful. The software is designed to recover lost or forgotten Excel file passwords using advanced recovery methods such as Brute Force and Mask attacks. It supports Excel files with password-to-open protection and helps recover passwords without modifying the original workbook.

Before purchasing, users can try the demo version to check the recovery process and verify the password recovery capability.

Has anyone used a reliable Excel password recovery solution for recovering passwords from protected XLS/XLSX files? I would appreciate any recommendations or experiences.
