How to force a worksheet to be protected again in Excel

Excel is a powerful tool that allows users to create and manipulate data in a variety of ways. One of the key features of Excel is the ability to protect worksheets, which can help prevent accidental changes or unauthorized access to sensitive data. However, there may be times when you need to re-protect a worksheet that has been unprotected. In this article, we will explore how to force a worksheet to be protected again in Excel.

Step 1: Open the Worksheet

The first step in re-protecting a worksheet in Excel is to open the worksheet that you want to protect. If the worksheet is already open, you can skip this step and move on to the next one.

Step 2: Click on the Review Tab

Once you have the worksheet open, click on the “Review” tab in the Excel ribbon. This tab contains all of the tools and options related to worksheet protection.

Step 3: Click on “Protect Sheet”

Next, click on the “Protect Sheet” button in the “Changes” group. This will open the “Protect Sheet” dialog box, which contains all of the options for protecting the worksheet.

Step 4: Enter a Password (Optional)

If you want to password-protect the worksheet, enter a password in the “Password to unprotect sheet” field. This will prevent anyone from unprotecting the worksheet without the password.

Step 5: Select Protection Options

Next, select the protection options that you want to apply to the worksheet. You can choose to allow users to select locked cells, select unlocked cells, format cells, format columns, format rows, insert columns, insert rows, insert hyperlinks, delete columns, delete rows, sort, use autofilter, use pivot table reports, edit objects, or edit scenarios. You can also choose to protect the worksheet’s structure, which prevents users from adding, moving, or deleting worksheets.

Step 6: Click “OK”

Once you have selected the protection options that you want to apply, click the “OK” button to protect the worksheet. The worksheet will now be protected according to the options that you selected.


Protecting a worksheet in Excel is an important step in ensuring the security and integrity of your data. By following these simple steps, you can easily re-protect a worksheet that has been unprotected, and ensure that your data remains safe and secure.
