How to Lock a Sheet in Microsoft Excel

Step 1. Preparing Your Worksheet for Locking
The first step in locking your Excel sheet is to ensure that all cells are set to be locked. Although Excel’s default is to have cells locked, if you’ve modified this setting in the past, you’ll need to reapply it. To do this, select every cell in your worksheet by pressing Ctrl+A, then right-click and choose ‘Format Cells.’ Navigate to the ‘Protection’ tab and make sure the ‘Locked’ checkbox is ticked. It’s important to note that this action doesn’t lock the cells yet; it merely prepares them to be locked when worksheet protection is activated.

Step 2. Activating Worksheet Protection
Now that your cells are set to be locked, you can enable worksheet protection. Head over to the ‘Review’ tab on the Excel ribbon and select ‘Protect Sheet.’ A dialog box will appear, asking you to input a password and specify the permissions for users. If you want to add a layer of security, enter a password that will be required to unlock the sheet. Remember this password well, as Excel doesn’t provide a recovery option. Alternatively, you can opt to not set a password by leaving the field blank.

Step 3. Configuring Editable Cells
In some cases, you might want to lock your sheet but leave certain cells editable. Before activating worksheet protection, select the cells you wish to remain editable. Right-click, choose ‘Format Cells,’ and then uncheck the ‘Locked’ box. With this setup, once worksheet protection is turned on, these selected cells can be edited while the rest stay locked.

Step 4. Protecting the Workbook Structure
To prevent modifications like adding, deleting, or renaming sheets within the workbook, you need to protect the workbook’s structure. Navigate to the ‘Review’ tab and click on ‘Protect Workbook.’ You’ll be prompted to enter a password, similar to sheet protection. Keep in mind that protecting the workbook structure is distinct from worksheet protection, and each serves different security purposes.
