Repair Microsoft Office Installation
Use the built-in Windows repair tool to fix damaged Office components that cause data connection errors.
This method will repair corrupted Office application files and restore the necessary backend components for data retrieval. Depending on your installation type (Click-to-Run or MSI), the exact repair steps might slightly differ.
Open the Windows Start menu, click on the gear icon to open Settings, and navigate to 'Apps' or 'Apps & features'.
Scroll through the application list to find your Microsoft Office installation, click on it, and select 'Modify'.
If you are using a Click-to-Run installation, choose 'Online Repair' and click 'Repair'. For an MSI-based installation, select 'Repair' and click 'Continue'.
Once the repair process finishes, restart your Windows computer, launch Excel, and test the external workbook connection again.

Frequently Asked Questions
Why does Excel fail to retrieve data from another workbook?
This often happens due to corrupted Microsoft Office installation files, broken network connections if the source file is on a shared drive, or file corruption within the source workbook itself.
Will running an Office repair delete my Excel files?
No, repairing Microsoft Office only reinstalls or fixes the application files and registry keys. Your personal workbooks, data, and settings will remain completely intact.
What if the Online Repair doesn't fix the Excel connection error?
If the repair fails, verify that the external workbook has not been moved, renamed, or deleted. If the file path is correct, you may need to completely uninstall and reinstall Microsoft Office.
