You’ve already put in the hard work to build your Excel spreadsheet and make your data shine. Now it’s time to share your work, but you have to make sure that your data is safe from accidental edits. Here’s how to protect your cells in Microsoft Excel.

By default, all of your cells will be locked when you set out to protect a spreadsheet. That means that they cannot be reformatted or deleted and the content inside can’t be edited. However, other users can still select each cell, something that you can change with the protection options. Here are some steps to get you started!

How to protect cells in Excel

1. First, we’ll walk through how to protect all of the cells in your sheet. This is ideal if you’re just sharing data that does not need to be changed. To start, head to the Review tab in the menu.

2. Now, select the Protect Sheet option. This will open a menu where you can make specific decisions on what permissions other users have.

3. Once you have specified permissions, click OK to protect your sheet.

Now that the entire sheet is protected, anyone who tries to edit one of the cells will see the following warning pop up:

The cells can only be edited again once you go back to the Protect Sheet menu and deactivate it. There are also steps that you can take to only protect part of your sheet. Those steps are as follows:

1. Select all of the cells that you don’t want to be locked. These will be able to be edited by team members or anyone that you share your sheet with.

2. Right-click on your selection and select Format Cells. Now click on the Protection tab.

3. Uncheck the Locked option which is active by default and then click OK.

4. Now go to the Review tab and select Protect Sheet. Once you select OK, all of the remaining locked cells will be protected as above.

Protecting your cells is just that easy, and now you know two ways to get the job done.
