Question details

Users need to display dates in the mm/dd/yyyy format on Excel for mobile, but the app changes the formatting applied from desktop versions.

Product: Microsoft Excel
Device & OS: iOS / iPadOS
Scenario: Viewing and formatting spreadsheet dates using the Excel mobile app on an iPhone or iPad.
Observed behavior: Dates properly formatted as mm/dd/yyyy in Excel for Windows or macOS automatically display incorrectly as m/d/yyyy when the spreadsheet is opened in Excel for iOS or iPadOS.

Before you start

Before modifying your device settings, ensure that your iPhone or iPad is updated to the latest version of iOS or iPadOS, and verify that you are running the most recent version of the Excel app from the App Store.

Solution 1Recommended

Adjust iOS Region and Language Settings

Because the Excel mobile app has fewer built-in custom formatting options than desktop versions, it often overrides custom dates by defaulting to your Apple device's system-wide regional settings.

Excel for iOS heavily relies on the device's native language and region parameters to determine how dates and numbers should be displayed. By aligning your iOS system settings with your desired date format, you can often force Excel to display dates correctly.

Open iOS Settings

Navigate to your device's home screen and tap on the gear icon to open the Settings app.

Navigate to Language & Region

Scroll down and tap on General, then select Language & Region from the available options.

Modify the Date Format

Tap on Region to ensure it is set to a locale that supports your desired formatting (such as United States). Then, check the Date Format option (if available on your iOS version) and ensure it matches the mm/dd/yyyy structure.

Restart Excel

Force close the Excel app by swiping up from the bottom of your screen, then reopen your spreadsheet to see if the dates render correctly.

System Limitations: Even with optimal regional settings, some highly customized desktop formats may still not translate perfectly due to inherent limitations in the Excel iOS app.

Solution 2

Submit Feedback via the Excel App

If tweaking regional settings does not resolve the mm/dd/yyyy formatting issue, reporting the missing functionality directly to Microsoft is the recommended action.

Frequently Asked Questions

Why does Excel for iPad change my date formats?

Excel for iPad and iPhone has a more limited set of custom cell formatting options compared to the Windows and macOS desktop versions. As a result, the mobile app often overrides custom formatting and forces dates to display according to your Apple device's system language and regional settings.

Can I manually apply the mm/dd/yyyy date format within the iOS Excel app?

Currently, the Excel app for iOS and iPadOS does not provide an advanced 'Format Cells' dialog that allows you to type out custom date structures like mm/dd/yyyy directly on the mobile device.

Will Microsoft fix the date formatting issue in Excel for iOS?

Microsoft continuously updates its mobile applications, but feature parity with desktop versions takes time. You can help prioritize this specific formatting issue by navigating to the Help menu in your Excel app and tapping 'Tell us what can be better' to submit direct feedback.
