Question details

Users are unable to open Excel files by double-clicking them in File Explorer following an update to version 16.0.17328.20648.

Product
Microsoft Excel
Device & OS
not provided
Scenario
Attempting to launch an existing Excel spreadsheet directly from File Explorer after a recent Office software update.
Observed behavior
The file fails to load when double-clicked. However, the same file opens successfully when using Excel's internal 'Open' and 'Browse' menu, and rolling back the software update resolves the issue.
Before you start

Verify your current Excel version number in Account settings and check if opening the file directly from within the Excel application works as a temporary workaround.

Solution 1Recommended

Use the Open Command within Excel

Bypass the double-click bug in File Explorer by opening files directly from within the Excel application.

Since the issue is isolated to the double-click action in File Explorer, opening the file manually from the software's built-in file menu will allow you to continue working uninterrupted.

1
Launch Excel

Open the Microsoft Excel application from your Start menu or desktop shortcut.

2
Access the Open Menu

Click on 'File' in the top-left corner of the interface and select 'Open'.

3
Browse for the File

Click the 'Browse' button, navigate to the folder location of your spreadsheet, select it, and click 'Open'.

Frequently Asked Questions

Why did my Excel files suddenly stop opening when I double-click them?

This issue is commonly caused by a bug introduced in a recent software update (such as Excel version 16.0.17328.20648). The update disrupts the file association process in Windows File Explorer, preventing the double-click action from successfully loading the file into Excel.

How can I open my Excel files while waiting for Microsoft to fix the bug?

You can easily bypass this issue by opening the Excel application first, clicking on 'File' > 'Open', and browsing your computer to select and open the spreadsheet manually.

Will rolling back the Excel update delete my spreadsheets?

No, rolling back to a previous version of Excel only affects the application software. Your saved spreadsheets, formulas, and personal data will remain completely intact and secure on your hard drive.

What is a sanitized test file and why do I need one?

A sanitized test file is a copy of your spreadsheet that has had all confidential, personal, or proprietary data removed or replaced with placeholder data. It is used to safely demonstrate a bug to technical support without compromising your privacy.
