Locking an Excel sheet to read-only is a great way to protect your data from being edited or altered by others. It’s a pretty simple process that ensures your hard work and sensitive data stay intact. By following a few straightforward steps, you can make sure your Excel sheet is viewable but not editable by anyone.
How to Lock Excel Sheet to Read Only
This guide will walk you through the steps needed to lock an Excel sheet so it can only be read and not modified. This is especially useful for sharing important data without the risk of it being changed.
Step 1: Open your Excel file
Open the Excel file that you want to lock to read-only.
Simply open the file as you normally would by double-clicking it or opening it from within Excel. Make sure the data you want to protect is in the correct sheet.
Step 2: Select the Review tab
Click on the "Review" tab located in the ribbon at the top of the Excel window.
The Review tab contains various tools for protecting and sharing your document. You’ll find the options for protecting sheets here.
Step 3: Click on Protect Sheet
Within the Review tab, find and click on the "Protect Sheet" button.
When you click "Protect Sheet," a dialog box will appear asking you to set a password and select the permissions you want to allow for users.
Step 4: Set your password
Enter a password in the dialog box to protect your sheet.
Setting a password ensures that only those who know the password can edit the sheet. Make sure to remember this password or store it securely.
Step 5: Choose permissions
Check or uncheck the boxes to determine what users can and cannot do with the sheet.
You can allow users to select locked cells, select unlocked cells, format cells, and more. For read-only, make sure to restrict editing permissions.
Step 6: Confirm and Apply
Click "OK" to confirm your settings and apply the protection to your sheet.
You may be prompted to re-enter the password to confirm. Once done, your sheet will be locked to read-only.
After you complete these steps, your Excel sheet will be locked, and users will only be able to view the data without making any changes. They will need the password to remove the protection and edit the sheet.
