How to Remove Encryption in Excelby ContributorUpdated May 12, 2020
Microsoft Excel contains encryption features to heighten security of your spreadsheets. Once enabled, the file cannot be viewed without entering the appropriate password. If you no longer require the encryption, the password can be easily removed.
Open the encrypted spreadsheet in Excel, which will require your password to Open and your password to Modify.
After you've entered your passwords to open the file, click "File" and then select "Passwords," the same way you would have to encrypt the file in the first place and create your passwords.
Delete the passwords in the window and press "OK" to remove the password from your spreadsheet.
Remember to save your changes so the file will remain decrypted.
