Actually, I am not familiar with MS Excel. I received an Excel file from my client. It kept asking me to enter a password when I tried to edit the cells. I tried some free online tools like LostMyPass, but they didn't remove the password protection. I decided to use a paid program and put all my hope on Passper for Excel. Luckily, I didn't waste my money on it. It removed the protection just within seconds. Thank you very much.
