Question details

The user needs to unprotect an Excel worksheet but is unable to do so because the system reports the entered password as incorrect.

Product: Microsoft Excel
Device & OS: not provided
Scenario: Attempting to unprotect a restricted worksheet to make edits or modifications.
Observed behavior: Excel rejects the provided password, keeping the worksheet locked and preventing the user from making any structural or content changes.

Before you start

Before attempting to recover the file, verify whether your Excel workbook is stored locally or on a cloud service like OneDrive or SharePoint, as cloud-stored files offer built-in version recovery options.

Solution 1Recommended

Verify Password Spelling and Keyboard Settings

Ensure that typos, capitalization errors, or keyboard settings are not causing the password to fail.

Excel worksheet protection passwords are strictly case-sensitive. A common reason for password rejection is an accidental keystroke or having the Caps Lock key engaged.

Check Caps Lock

Press the Caps Lock key on your keyboard to ensure it is turned off before typing.

Test in a text editor

Type your password into a visible text editor like Notepad to verify the spelling and capitalization, then copy and paste it into the Excel password prompt.

Try alternative passwords

Test standard variations or previous passwords you frequently use for document protection, as it is easy to mistake which password was applied.

Bypass Limitations: Microsoft Support cannot provide instructions, utilities, or assistance for intentionally bypassing or removing forgotten worksheet protection.

Solution 2

Restore an Earlier Version via OneDrive or SharePoint

If the file is synced to a cloud service, you can revert to a version saved before the password was applied or changed.
