How to encrypt Excel file with password?

Excel makes it easy to encrypt spreadsheets by locking them with a password.

It takes just three simple steps:

  • Go to File > Info > Protect Workbook > Encrypt with Password.
  • Enter the desired password and click OK.
  • Confirm the password. 


Keep your password in a safe place. If you lose or forget it you cannot restore or delete it.

However depending on what you want to protect the method you use may vary slightly.

If you add a password you will need to enter the password every time you open the file.

If you want to remove the password you must follow these steps:

  • Choose File > Protect Workbook > Encrypt with Password.
  • Remove the password and click the OK button.
  • Remember to save the file to apply the changes.

Permit read-only access 

Setting up basic encryption is easy but Excel actually offers different options when it comes to password protection. For example someone can open a document but not edit it.

Implementing such a system is very easy.

  • Click File > Save As > Browse > Services. Select General Settings from the drop-down menu.

Here you will notice that there are two different fields: Open Password and Change Password. You can leave the latter blank if you want to restrict editing rights without restricting access to the document itself.

Protecting a worksheet

If your document contains multiple sheets you can limit editing permissions to one or more sheets not the entire book.

  • Click the Reviewing tab and then click Protect Sheet.

Here you will be able to enter the desired password for the current sheet.

However you'll notice that there's also a series of tabs that allow all users to access certain features. This can be handy if you want them to be able to sort the column without any major changes.

  • Select the entire table. The easiest way to do this is to press a special button located at the intersection of vertical (row numbering) and horizontal (column designation). However you can also use the hotkey by pressing CTRL+A.
  • Press the right mouse button.
  • Click Format Cells in the menu.
  • Click the Protection tab in the window that appears.
  • Remove the check mark from the protected cell item.
  • Click OK.

The second way to protect cells 

As mentioned above the second method of protecting cells in Excel from changes is not much different from the first method. The following are detailed instructions.
