Protect a workbook

To prevent other users from viewing hidden worksheets, adding, moving, deleting, or hiding worksheets, and renaming worksheets, you can protect the structure of your Excel workbook with a password.

Protect the workbook structure

To protect the structure of your workbook, follow these steps:

1. Click Review > Protect Workbook.

   

2. Enter a password in the Password box.

   Important

   The password is optional. If you do not supply a password, any user can unprotect and change the workbook. If you do enter a password, make sure that you choose a password that is easy to remember. Write your passwords down and store them someplace safe. If you lose them, Excel cannot recover them for you.

3. Select OK, re-enter the password to confirm it, and then select OK again.

How can I tell if a workbook is protected?

On the Review tab, see the Protect Workbook icon. If it's highlighted, then the workbook is protected.

If you click on the bottom of a sheet inside your workbook, you will notice that the options to change the workbook structure, such as Insert, Delete, Rename, Move, Copy, Hide, and Unhide sheets are all unavailable.

The Protect Workbook option in the Info menu also indicates that the workbook's structure is protected. To view this option, click File > Info > Protect Workbook.

You cannot open a workbook or document that has been password-protected in the Windows-based version of Excel or if the password is longer than fifteen characters. If you want to open the file in Excel for Mac, ask the Windows-based author to adjust the password length.

Excel for the web can open and edit workbooks protected by a password. Passwords can't be added, changed, removed, or recovered from Excel for the web.

If you want to add a password to a workbook you are working on in Excel for the web, and you have Excel desktop application, use the Open in Excel button to open the workbook and password protect the workbook. But going forward, you'll only be able to view the file on web -- to make changes to the workbook, open it in your desktop version of Excel.

• Select Open in Excel and password protect the workbook.
