How to Open a Password Protected Excel File on Mac if Forgotten
Question details
The user has forgotten the password to an encrypted Excel workbook on Mac and needs a way to open it, as alternative methods like Apple Numbers fail to remove the protection or cause data loss.

- Product
- Microsoft Excel
- Device & OS
- macOS
- Scenario
- Attempting to open, view, or edit a password-protected Excel file without knowing the correct password.
- Observed behavior
- The Excel file prompts for a password and blocks access. Attempting to bypass the security by opening the file in Apple Numbers either still prompts for the password or results in missing formulas and broken formatting.
Before looking for complex bypass methods, double-check Apple Keychain Access or your third-party password manager to see if you previously saved the workbook password.
Recover Through Backups and Original Sources
Since Microsoft does not provide a supported way to bypass workbook encryption, checking for previous versions or contacting the creator is the safest and most effective method.
Strong workbook encryption is designed to be uncrackable without the correct password. Relying on original sources or local backups is the only guaranteed way to retrieve your data safely.
Open the Keychain Access app on your Mac (located in Applications > Utilities) and search for the name of the Excel file to see if the password was saved locally.
If your file is synced to OneDrive, Google Drive, or Dropbox, log into the web interface, right-click the file, and select 'Version History' to see if an older, unprotected version is available.
If you received the file from a colleague or client, contact them directly to securely request the password or ask them to send an unprotected copy.
Restore an Unprotected Version via Time Machine
If the password was added recently, you can restore an earlier state of the workbook from your Mac's built-in Time Machine backup.
Secure and Manage Your Spreadsheets with WPS Office
While no software can bypass secure Excel workbook encryption without the password, WPS Office provides a lightweight, highly compatible, and free alternative to Microsoft Office for Mac. You can easily open, edit, and apply robust password protection to your spreadsheets.
- 1. Download for Mac: Visit the official WPS Office website and download the Mac version of the software.
- 2. Open Your Spreadsheets: Launch WPS Spreadsheets and open any existing Excel files seamlessly.
- 3. Manage Document Security: Navigate to the 'Menu' > 'File' > 'File Encryption' to securely add or update passwords for your workbooks.

Frequently Asked Questions
Can Apple Numbers remove the password from an Excel file?
Generally, no. While older versions of Apple Numbers could sometimes ignore basic worksheet cell restrictions, modern workbook-level encryption requires the correct password to open, even in Numbers. Furthermore, opening complex Excel files in Numbers often breaks advanced formulas and formatting.
Are third-party password removal tools safe to use on Mac?
Security experts strongly advise against using unverified third-party or online password removal tools. Uploading your locked spreadsheet to these services can expose sensitive personal or corporate data, and downloaded "cracking" software may contain malware that compromises your Mac.
What is the difference between worksheet protection and workbook encryption?
Worksheet protection simply locks specific cells or sheets from being edited but still allows you to open and view the file. Workbook encryption (or a 'password to open') encrypts the entire file, meaning you cannot even view the contents without the correct password.
