Adding a password to an Excel file will keep sensitive information in your workbook secret. This is especially true if the file is being emailed over an unsecured connection.

I’m sure there are some Excel files on your computer that either contain personal or business data. These files should have a layer of security by applying a password to keep the wrong people out of your business. I will review how to set up a password to protect a whole file.

1. Choose File

The first step is to click on the file menu button in the top left-hand corner of your workbook.

2. Choose Protect Workbook

You should already be in the info section of the file menu by default. If you aren't, select info from the file menu. Next, Choose the first option "Protect Workbook."

3. Choose Encrypt With Password

Next, choose the option "Encrypt with Password" and be prepared to use a password.

4. Enter Password Twice

Now enter a password in the encrypt document window. After you click OK, enter the same password again into the new window.

Password Protected

At this point, the workbook is now password protected.

Once the Excel file is closed, the password that was previously saved will need to be entered to access the file.

Be sure that your password is not too complex as you will not be able to unlock the workbook without it.
