Fix Missing Excel Date Formatting Options in Samsung DeX Mode
Question details
Users are unable to find or access specific date formatting options in Microsoft Excel while operating via Samsung DeX mode.

- Product
- Microsoft Excel
- Device & OS
- Samsung DeX (Android)
- Scenario
- Editing or formatting spreadsheets on a Samsung mobile device connected to an external monitor via DeX desktop mode.
- Observed behavior
- Date formatting options are missing, restricted, or display differently compared to the standard Android or Windows versions of Excel.
Ensure your Samsung device is securely connected to your external display and save any open workbooks before restarting your DeX session or updating applications.
Update Apps and Restart Samsung DeX
Updating your software and restarting the DeX environment can resolve temporary UI glitches causing missing formatting menus.
Samsung DeX dynamically scales Android applications to fit a desktop environment. Sometimes, outdated apps or rendering bugs prevent specific menus, like the date formatting options in Excel, from appearing correctly.
Ensure Microsoft Excel was installed directly from the Google Play Store and not side-loaded, as third-party APKs may lack full DeX compatibility.
Open the Google Play Store, search for Microsoft Excel, and tap the 'Update' button if a new version is available. Also, check for device firmware updates in your Samsung Settings.
Disconnect your device from the monitor or exit DeX mode via the notification panel. Reconnect your device to start a fresh DeX session and open your Excel workbook.

Apply Formatting in Standard Android Mode
If DeX mode inherently restricts the feature by design, use the standard Android interface on your phone screen to apply the necessary date formats.
Try WPS Office for a Seamless Desktop Experience on Android
If Microsoft Excel restricts your formatting tools in DeX mode, WPS Office offers a robust, desktop-class spreadsheet editor that excels in Android desktop environments.
- 1. Download WPS Office: Search for WPS Office in the Google Play Store on your Samsung device and install the app.
- 2. Open Your Spreadsheet: Launch WPS Office while in DeX mode and open your existing .xlsx file without losing any data.
- 3. Apply Date Formats Easily: Right-click the cells or navigate to the 'Format Cells' menu on the top ribbon to access complete date formatting controls.

Frequently Asked Questions
Why does Excel look different in Samsung DeX mode?
Samsung DeX forces mobile apps into a scalable desktop window. While some apps are fully optimized for this, Excel for Android adapts its interface, which can sometimes hide or restrict certain advanced formatting menus found on the standard mobile or Windows desktop versions.
Does Samsung DeX run the full Windows version of Excel?
No, Samsung DeX runs the Android version of the Excel app from the Google Play Store. It does not run the full Windows or Mac desktop application, which is why complex desktop features or extensive formatting options may be missing.
How do I force Excel to update on my Samsung device?
Open the Google Play Store, tap your profile icon in the top right corner, select 'Manage apps & device', and check for pending updates for Microsoft Excel under the 'Updates available' section.
Are there alternative apps that provide better spreadsheet formatting in DeX?
Yes, alternatives like WPS Office are highly optimized for both mobile screens and desktop modes (like Samsung DeX) on Android. They often provide a more familiar, feature-rich interface for editing spreadsheets and applying custom cell formats.
