How to Lock Cells in Excel

Locking cells in Excel is an essential feature when you want to protect your data from unintended changes. Here's how you can do it:

2. Modify Cell Protection Settings: Right-click on the selected cells and choose 'Format Cells'. Go to the 'Protection' tab. Here, you will see the 'Locked' option checked by default. If you want to unlock certain cells, uncheck this box.
3. Protect the Worksheet: Go to the 'Review' tab on the Ribbon and click on 'Protect Sheet'. You can set a password to unprotect the sheet later. Here, you can also specify what users are allowed to do, such as selecting locked or unlocked cells, formatting cells, etc.
4. Confirm the Protection: After setting your options, click 'OK'. Your worksheet is now protected, and the cells you left locked cannot be edited by others.
