  • Open Your Excel File: Start by opening the Excel file you wish to protect.
  • Click on ‘File’: Navigate to the ‘File’ tab located in the upper-left corner of Excel.
  • Select ‘Save As’: In the File menu, choose the ‘Save As’ option.
  • Click on ‘Browse’: This allows you to select where you want to save the file.
  • Click on ‘Tools’ in the Save Window: In the Save window, look for the ‘Tools’ option located near the Save button.
  • Select ‘General Options’: From the drop-down menu under Tools, select ‘General Options’.
  • Set Passwords: In the General Options dialog box, enter the passwords in the provided fields:
    • Password to Open: Set this password if you want users to enter a password to open the document.
    • Password to Modify: Use this option if you want the document to be viewable without a password, but a password is needed to make changes.
  • Confirm Your Passwords: After setting your passwords, you’ll be prompted to confirm them.

  • Microsoft Excel does not offer a way to recover lost or forgotten passwords.

Securing your Excel files with a password is a straightforward yet powerful way to protect your sensitive data.

This guide has walked you through each step of the process, demystifying what might seem like a complex task into an easy and manageable one.

Remember, the strength of your file’s security largely depends on the complexity and confidentiality of the password you choose. It’s essential to create a strong, unique password and keep it in a safe place. Be mindful that losing this password could mean losing access to your data, as Excel does not provide a recovery option for forgotten passwords.
