Fix Excel .xlsx Files Not Opening When Double-Clicked
Question details
The user is unable to open .xlsx spreadsheet files by double-clicking them, even though older .xls files open without any issues.
- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Attempting to launch modern Excel workbooks (.xlsx) directly from the Windows File Explorer.
- Observed behavior
- Double-clicking the .xlsx file fails to open it or triggers an error, whereas .xls files open normally.
Ensure that your computer currently has a spreadsheet application installed, such as Microsoft Excel or WPS Office, that actively supports the modern .xlsx file format.
Manually Set the Default App for .xlsx Files
Reassign the Windows file association for .xlsx files so that they are explicitly directed to open with Microsoft Excel.
Incorrect file associations often happen after a software update or when multiple spreadsheet programs have been installed. Manually linking the .xlsx extension to Excel typically resolves the issue immediately.
Locate an .xlsx file on your computer and right-click it to open the context menu.
Click on 'Open with' and then select 'Choose another app' from the expanded list.
Select 'Excel' from the list of available applications.
Check the box next to 'Always use this app to open .xlsx files' and click the 'OK' button to save your changes.
Repair Microsoft Office through Control Panel
Run a quick repair on your Microsoft Office installation to fix broken registry keys and damaged program files.
Open and Edit .xlsx Files Instantly with WPS Office
If repairing Microsoft Office fails or you are dealing with conflicting software installations, you can instantly regain access to your files using WPS Office. It fully supports .xlsx files and can easily be set as your default spreadsheet application.
- 1. Install WPS Office: Download and install the free version of WPS Office from the official website.
- 2. Access Open With Menu: Right-click the problematic .xlsx file, hover over 'Open with', and click 'Choose another app'.
- 3. Select WPS Spreadsheet: Find and select 'WPS Spreadsheet' in the application list.
- 4. Save as Default: Check 'Always use this app to open .xlsx files' and click 'OK' to immediately open your file.
Frequently Asked Questions
Why do my older .xls files open properly but not my new .xlsx files?
The older .xls and newer .xlsx formats use different Windows file associations. A system update or conflicting application can easily break the association for .xlsx while leaving the older .xls configuration completely intact.
Can having multiple versions of Office installed cause .xlsx files not to open?
Yes, having multiple versions of Microsoft Office installed on the same computer can create registry conflicts. Windows may become confused about which specific version's executable file should be triggered when you double-click an .xlsx file.
Will running an Office Quick Repair delete my personal spreadsheets?
No, running a Quick Repair from the Windows Control Panel only scans and fixes corrupted software files, shortcuts, and registry keys. Your personal data, saved workbooks, and settings are perfectly safe.
What if Excel is missing from the 'Choose another app' menu?
If Excel does not appear in the initial list, click 'More apps', scroll to the bottom, and select 'Look for another app on this PC'. From there, navigate to your Program Files folder (usually under Microsoft Office > root > OfficeXX) and manually select the EXCEL.EXE file.
