Apply cell protection: Once you have checked the “Locked” checkbox, click “OK” to apply the cell protection settings.

After following these steps, the selected cells will be locked and protected from any modifications. However, it’s important to note that simply locking the cells may not be sufficient if multiple users have access to the spreadsheet. To further enhance security, you can specify which users have permission to edit the locked cells.

To allow only specific users to edit locked cells, you can utilize Excel’s password protection feature. With this method, you can assign a password that grants editing rights to authorized individuals while restricting others from making any changes. Here’s how you can set up password protection for locked cells:

Select the locked cells: Choose the cells you want to protect and prevent editing.
Right-click and choose “Format Cells”: Similar to the previous method, right-click on the selected cells and select “Format Cells.”
Navigate to the “Protection” tab: Within the Format Cells dialog box, go to the “Protection” tab as before.
Check the “Locked” checkbox: Once again, ensure that the “Locked” checkbox is checked for the selected cells.
Set a password for the sheet: To assign a password, click on the “Review” tab in Excel’s ribbon. Then, click on “Protect Sheet” and provide a strong, unique password.
Specify user permissions: As part of the password protection process, you can allow specific users or groups to edit the locked cells by granting them the password.

By following these steps, you can customize access to your locked cells and ensure that only authorized users have the ability to modify important data. This adds an additional layer of security to your Excel spreadsheets, safeguarding against unauthorized editing and potential data breaches.

Remember, while protecting cells and restricting editing is crucial for maintaining data integrity, it’s also essential to strike a balance between security and usability. Ensure that you keep track of passwords and provide necessary access to individuals who require it.
