How to Unlock Excel Sheet: A Step-by-Step Guide to Unprotect Your Data

Unlocking an Excel sheet is a simple process that involves removing a password or a restriction set within the workbook. To unlock an Excel sheet, you’ll need to open the workbook, navigate to the Review tab, and then select the Unprotect Sheet option. You’ll be prompted to enter a password if the sheet is password-protected. After this, the sheet will be unlocked, allowing you to make any necessary changes.
