Ensuring the security of our digital documents is essential in today's cyber threat landscape. One popular way to safeguard sensitive information stored in an Excel file is by password protecting it. This security measure adds an extra layer of protection, preventing unauthorized access to your data.

Steps to Password Protect an Excel File:

1. Open the Excel file you want to protect.
2. Click on 'File' in the top-left corner of the Excel window.
3. Select 'Info' from the menu on the left.
4. Click on 'Protect Workbook' and then 'Encrypt with Password.'
5. Enter your desired password in the prompt that appears, then click 'OK.'
6. Re-enter the password to confirm and click 'OK.'

It is crucial to choose a strong and unique password when securing your Excel file. Avoid using easily guessable passwords such as 'password123' or '123456'.

By following these simple steps, you can enhance the security of your Excel files and protect your sensitive information from unauthorized access.
