Protect the Sheet: To Prevent Others from Unlocking the Cells, Protect the Worksheet
If you want to prevent others from unlocking the cells that you have protected, you can protect the worksheet.
- Go to the "Review" tab: To protect the worksheet, go to the "Review" tab in the Excel ribbon.
- Locate the "Protect" group: On the "Review" tab, locate the "Protect" group. This group is usually located on the right side of the ribbon.

Once you have entered a password (or left it blank), click on the "OK" button to protect the worksheet.
Your worksheet is now protected and others will not be able to unlock the cells that you have protected.
Use Password: You Can Set a Password to Protect the Worksheet and Prevent Unauthorized Changes
When you protect a worksheet, you have the option to set a password. This password is used to prevent others from unprotecting the worksheet and making changes to the locked cells.
To set a password when you protect a worksheet, follow these steps:
- Go to the "Review" tab in the Excel ribbon.
- Locate the "Protect" group on the "Review" tab.
- Click on the "Protect Sheet" button in the "Protect" group.

Your worksheet is now protected and others will not be able to unprotect it without the password.
It is important to choose a strong password that is not easy to guess. You should also keep your password safe and secure. If you lose your password, you will not be able to unprotect the worksheet and make changes to the locked cells.
If you forget your password, you can try to recover it using a password recovery tool. However, there is no guarantee that you will be able to recover your password. Therefore, it is important to choose a password that you will remember and keep it safe.
Locked Cells Are Read-Only: Locked Cells Cannot Be Edited or Modified
One of the most important things to know about locked cells is that they are read-only. This means that you cannot edit or modify the data in locked cells.
If you try to edit a locked cell, you will see a message that says "The cell is protected and cannot be changed." You will also see a small lock icon in the bottom-right corner of the cell.
There are a few ways to unlock cells so that you can edit them:
- Unprotect the worksheet: You can unprotect the worksheet to unlock all of the locked cells on the worksheet. To do this, go to the "Review" tab in the Excel ribbon, locate the "Protect" group, and click on the "Unprotect Sheet" button.
- Unlock individual cells: You can also unlock individual cells without unprotecting the worksheet. To do this, select the locked cells that you want to unlock, go to the "Home" tab in the Excel ribbon, locate the "Cells" group, and click on the "Format" button. In the "Format Cells" dialog box, select the "Protection" tab and uncheck the "Locked" checkbox. Click on the "OK" button to apply the changes and close the dialog box.
Once you have unlocked the cells, you will be able to edit the data in those cells.
It is important to note that locked cells are still visible to other users. This means that others can see the data in locked cells, even if they cannot edit it.
