How to Fix Old Password Not Unprotecting an Excel Workbook
Question details
The user is unable to unprotect an Excel assessment workbook using a previously working password.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to unlock a protected workbook or worksheet using an existing, known password.
- Observed behavior
- The password is unexpectedly rejected, or the Excel unprotect feature fails to respond, leaving the workbook locked.
Ensure your Caps Lock key is turned off and verify you are opening the correct version of the workbook, as passwords are case-sensitive and multiple copies of a file may have different passwords.
Verify Password Input and File Integrity
Check for common typing errors or temporary software glitches that might prevent the password from being recognized.
Passwords in Excel are strictly case-sensitive. Ensure the Caps Lock key on your keyboard is disabled and carefully re-enter the password.
Open Notepad or another plain text editor and type your password there to confirm your keyboard is outputting the correct characters. Copy the text and paste it into the Excel password prompt.
Close Microsoft Excel completely and reopen the workbook. Occasionally, temporary background glitches can cause the Unprotect feature to malfunction and reject correct passwords.
Contact the Workbook Owner or Administrator
Use authorized channels to recover access if the password has been changed or forgotten.
Manage Your Spreadsheets Securely with WPS Office

Frequently Asked Questions
Can Microsoft Support help me reset my Excel password?
No, Microsoft support communities and official support agents cannot provide instructions or tools for bypassing, defeating, or resetting password protection due to strict security policies.
Why did my Excel password suddenly stop working?
This can happen if another user with access changed the password, if the file became corrupted, or if there is a temporary software glitch preventing the Unprotect feature from processing the input correctly.
Does case sensitivity matter in Excel workbook protection?
Yes, Excel passwords are completely case-sensitive. Always verify that your Caps Lock key is off and that you are using the exact capitalization when attempting to unprotect a sheet.
Is it safe to use online Excel password removers?
It is highly discouraged. Third-party password removal tools or websites pose severe security risks, may steal your sensitive data, and often contain malware or phishing links.
