How to Lock & Protect Excel Workbook From Editing

Excel spreadsheets are widely used for online collaboration in companies big and small, especially since the release of the latest version. For example, if you want to share an Excel file so that multiple users can work on it simultaneously, the 365 version includes powerful co-authoring features to collaborate online. However, let’s say that you only want certain parts to be editable because there are complex formulae or reference cells that should not be modified.

In this article, you’ll learn how to lock an Excel spreadsheet from editing according to the level of protection you’d like to apply. There are 5 different protection methods, including “Mark as Final”, protecting it with a password with a read-only status, and protecting specific cells.

How To Protect An Excel Workbook From Editing?

One of the great advantages of using Excel spreadsheets is that it offers different layers of protection and different ways to do so. Here, you’ll learn how to protect an Excel workbook using 5 quick and efficient methods.

Protect an Excel workbook from editing by using Mark as Final

The “Mark As Final” is a protection feature for your whole workbook. This is how you can protect an Excel workbook from editing by others.

1. 1. Open the Excel file you’d like to “Mark As Final”. Go to File > Info > Protect Workbook > Mark as Final.

1. 2. Click “OK” to save with that status.

1. 3. Excel reminds you about the “Mark As Final” status and how to know if a file has been set to “Final” by checking the status bar, located at the bottom. Click “OK” to continue.

1. 4. Check the status by reopening the file. Excel should now prompt you with the following warning message. To edit, you simply need to click on “Edit Anyway”.

As you can see, more than a full protection measure, it’s a warning for other users to avoid editing since you can easily remove the “Mark As Final” status by clicking on “Edit Anyway”, as shown above. If you want to protect your workbook from editing completely, then you will have to protect it with a password.

Protect an Excel workbook from editing with a password

If you encrypt your Excel Workbook with a password, you’re restricting others from opening the file. Unless you provide them with the password, they won’t be able to view or edit the data.

1. 1. Open your Excel file and go to File > Info > Protect Workbook > Encrypt with Password.

1. 2. Enter the password and click “OK” to save. Make sure that you read Microsoft’s “Caution” message passwords.

1. 3. Re-enter the password to confirm. Click “OK”.

1. 4. To check that this method worked, reopen your workbook. Excel should automatically prompt a message to enter a password.

Protect an Excel workbook from editing but allow read-only

Allowing other users to open as “Read-Only” is a weaker level of protection since any user can still open the file and enable editing themselves. However, just like “Mark As Final”, it can serve as a precautionary measure for your team to be more careful when editing.

1. 1. Open the Excel workbook you’d like to protect with “read-only” and head over to File > Info > Protect Workbook > Always Open Read-Only.

1. 2. Any user who tries to open the file will get the following warning message. To continue editing, simply click on “Edit Anyway”.

As you’ve seen, you simply need to click on “Edit Anyway” to be able to make changes. However, it’s useful to learn how to remove this feature as there may be other reasons why you may want to remove read-only from Excel.

Protect the structure of an Excel workbook from editing

Protecting the structure of your workbook will restrict others from deleting current sheets or adding new ones; in other words, it restricts others from using structural commands. This is how you can protect your Excel workbook from structural edits.

1. 1. Go File > Info > Protect Workbook > Protect Workbook Structure.

1. 2. Enter a password and click the “OK”.

1. 3. Confirm the password by entering again. Click “OK” to finish.

1. 4. Double-click on a sheet name to rename, and Excel should prompt you with the following message.

After applying this option, anyone can open your Excel document, but they can’t access its structural commands, including adding a sheet, changing the name, or deleting any existing sheets.

Protect specific cells in an Excel workbook from editing

To protect specific cells, you will need to protect the sheet. This is how to protect an Excel sheet from editing and copying specific cells.

1. 1. Select the cell range you want to lock from editing. Right-click on the selected range and then click on “Format Cells” from the drop-down menu.

1. 2. Go to the “Protection” tab and check the box next to the “Lock cells” option. As Microsoft warns you, you’ll need to protect the sheet so this has an effect. Click “OK” to proceed.

1. 3. Go to the “Review” tab and click on “Protect Sheet”.

1. 4. Enter the password and make sure the option “Protect worksheet and contents of locked cells” is enabled. Click “OK”.

1. 5. Re-enter the password to confirm and click “OK” to finish.
