How to Fix Excel Protection Password Invalid After Migration to SharePoint
Question details
Users are experiencing issues where their original Excel protection passwords are not accepted after migrating files to SharePoint Online.
- Product
- Microsoft Excel, SharePoint Online
- Device & OS
- not provided
- Scenario
- Migrating Excel files from a local Windows server to SharePoint Online.
- Observed behavior
- Excel files no longer accept their original protection passwords, blocking users from unprotecting or accessing the secured data.
Ensure you have access to the original Excel files on the source Windows server and verify that you know the correct protection passwords before proceeding.
Remove and Reapply Protection Passwords During Migration
Since file-level protection can sometimes conflict during the SharePoint migration process, removing passwords beforehand and reapplying them in SharePoint is the most reliable workaround.
Excel file-level protection is stored within the file itself and is separate from SharePoint site permissions. Transferring heavily encrypted files can sometimes result in synchronization glitches that cause password prompts to reject valid credentials.
Access the source Excel file on your original Windows server using the correct current password.
Navigate to the 'Review' tab on the ribbon and click 'Unprotect Sheet' or 'Unprotect Workbook'. Enter your password to remove the security.
Save the unprotected Excel file and proceed to migrate it to your SharePoint Online document library.
Open the migrated file directly from SharePoint, go back to the 'Review' tab, click 'Protect Sheet' or 'Protect Workbook', and set a new password.
Verify File Integrity and Migration Tool Logs
Check if the file was corrupted during the transfer, which can cause password prompts to fail even if the correct password is used.
Use WPS Office for Seamless and Secure Spreadsheet Management
If you frequently encounter password and compatibility issues with Microsoft Excel during cloud migrations, consider switching to WPS Office. It provides robust file encryption, seamless cloud integration, and excellent compatibility with Microsoft Office formats without the heavy subscription fees.
- 1. Download WPS Office: Visit the official WPS website and download the free WPS Office installer.
- 2. Install the software: Run the installer and follow the on-screen instructions to set up the software on your device.
- 3. Open your spreadsheets: Launch WPS Spreadsheets and open your .xlsx files to enjoy seamless compatibility and robust protection.
Frequently Asked Questions
Does SharePoint Online change Excel file passwords during migration?
No, SharePoint Online does not alter internal file-level protection passwords. If a password fails after migration, it is typically due to file corruption during the transfer or a syncing error.
How do SharePoint permissions interact with Excel workbook protection?
They operate entirely independently. SharePoint permissions control who can view, edit, or download the file from the site, while Excel protection controls access or modifications to the contents within the file itself.
Can I bulk remove Excel passwords before a SharePoint migration?
Excel does not have a built-in feature to bulk remove passwords. You must either remove them manually one by one or use a custom VBA macro if you have the credentials for all the files.
What should I do if I forgot the original Excel protection password?
If you have forgotten the password for an Excel file, you will not be able to unprotect it through standard methods. Microsoft does not provide a way to recover lost workbook or sheet passwords.
