Fix Excel Files Not Opening by Double-Clicking in Windows 10
Question details
The user is unable to open Excel spreadsheets by double-clicking them in Windows File Explorer, although the files can be opened normally from within the Excel application itself.

- Product
- Microsoft Excel 2013
- Device & OS
- Windows 10
- Scenario
- Attempting to open an .xls or .xlsx file directly from the Windows File Explorer desktop or folder.
- Observed behavior
- Double-clicking the file fails to launch it in Excel, indicating broken file associations, software misconfiguration, or corrupted registry keys.
Before changing system configurations, open the Excel application first and try opening the file from the File > Open menu to ensure the file itself is not corrupted.
Reset File Associations in Windows 10
Manually reassign the default application for .xls and .xlsx files to Microsoft Excel to restore the double-click functionality.
The most common reason files won't open on double-click is that Windows has lost the correct association between the file extension and the application.
Open File Explorer and navigate to a folder containing any .xls or .xlsx file.
Right-click the Excel file, hover over 'Open with', and select 'Choose another app'.
Click on 'Microsoft Excel' from the list of applications. If it is not listed, click 'More apps' to find it.
Check the box that says 'Always use this app to open .xlsx files' and click OK.

Frequently Asked Questions
Why do my Excel files only open from inside the application?
This typically occurs when the Windows file association is broken or pointing to a corrupted executable path. Windows does not know how to send the double-click launch command to Excel, but the application itself functions normally when opened directly.
Will repairing Microsoft Office delete my saved spreadsheets?
No. Running the Office Repair tool from the Control Panel only fixes the software application files, installation folders, and registry entries. It will not touch, alter, or delete any of your personal documents or data.
What should I do if resetting file associations does not work?
If resetting file associations fails, you can try creating a new Windows user profile to rule out profile corruption, running the 'sfc /scannow' command in an elevated Command Prompt to fix core Windows system files, or reinstalling Microsoft Office completely.
Can I use WPS Office to open my inaccessible Excel files?
Yes. WPS Office provides full compatibility with all standard Excel formats (.xls and .xlsx). By installing WPS Office and setting it as your default spreadsheet program, you can immediately bypass the Windows-to-Excel association error and access your files.
