Frequently Asked Questions

How can I protect a specific cell in Excel?

First, select the cell you want to protect, then right-click and choose “Format Cells.” In the “Format Cells” dialog box, go to the “Protection” tab and check the “Locked” checkbox.

Click “OK” to close the dialog box. After that, you can protect the entire sheet using the “Protect Sheet” option under the “Review” tab in the Excel ribbon. Now, the specific cell will be locked, and its contents cannot be changed unless the worksheet is unprotected.

What is the difference between locking cells and protecting a sheet in Excel?

Locking cells in Excel allows you to prevent specific cells from being edited, while protecting a worksheet enables you to restrict various actions, including editing, formatting, and sorting, on the entire worksheet.

When you lock a cell, you’re only preventing direct changes to its content, but protecting a sheet applies a broader range of restrictions.

Check the “Locked” checkbox and click “OK.” After that, protect the entire sheet using the “Protect Sheet” option under the “Review” tab in the Excel ribbon.

This will prevent any changes to the locked cells, including the formulas they contain.

How do I unlock a cell in Excel with a password?

To unlock a cell in Excel with a password, you’ll first need to unprotect the sheet. Go to the “Review” tab, click “Unprotect Sheet,” and enter the password if one was set during protection.

Then, right-click on the cell you want to unlock, choose “Format Cells,” go to the “Protection” tab, and uncheck the “Locked” checkbox. Click “OK,” and the cell will now be unlocked and editable. Don’t forget to protect the sheet again after making the necessary changes.
