7. What Does the ‘Unable to Open Workbook’ Message Mean in Spreadsheet Compare?

Encountering the “Unable to open workbook” message in Spreadsheet Compare typically indicates that one or both of the Excel files you are trying to compare are password protected. This protection prevents the application from accessing the file content.

Reasons for the Message:

How to Resolve the Issue:

  - Right-click the file in File Explorer, select Properties, and go to the Security tab to check your permissions.
3. Repair Corrupt File:
  - If you suspect file corruption, try opening the file in Excel and using the built-in repair tool.
  - In Excel, go to File > Open > Browse, select the file, click the dropdown arrow next to the Open button, and choose Open and Repair.
Additional Tips:

4. Continue with Comparison:
  - After entering the correct passwords, Spreadsheet Compare will proceed with the comparison process.
Important Considerations:
- You must have the password to open the file, not just the password to modify it.
- Spreadsheet Compare does not bypass or crack password protection; it requires the correct password to function.
