Product
Microsoft Excel
Device & OS
not provided
Scenario
Opening and viewing migrated Google Sheets files in Microsoft 365.
Observed behavior
Excel retains English (United States) or displays an Armenian locale, resulting in incorrect date formats that cannot be easily changed to English (UK) defaults.
Before you start

Ensure your Windows operating system is fully updated and check that your default Windows region is set to the United Kingdom before adjusting application-specific settings.

Solution 1Recommended

Adjust Windows and Excel Regional Language Settings

Synchronize your Windows system locale with Excel's language settings to ensure default date formats are applied correctly across all new and opened workbooks.

Excel often relies on the underlying Windows operating system to determine how dates, times, and currencies are formatted. If there is a mismatch between Windows and Microsoft 365 settings, downloaded files may default to incorrect locales.

1
Change Windows Regional Format

Open Windows Settings, go to 'Time & Language', and select 'Region'. Change the 'Regional format' dropdown to 'English (United Kingdom)'.

2
Access Excel Options

Open Microsoft Excel, click on 'File' in the top-left corner, and select 'Options' at the bottom of the menu.

3
Modify Language Preferences

Navigate to the 'Language' tab in the Excel Options window.

4
Set UK English as Preferred

Under 'Office display language' and 'Office authoring languages and proofing', ensure English (United Kingdom) is added and set as the preferred language.

5
Restart Application

Click 'OK' and restart Microsoft Excel for the new regional settings to take effect.

System Synchronization: Updating the Windows region settings will automatically correct the default date format for most newly opened files in Microsoft 365.

Frequently Asked Questions

Why do migrated Google Sheets files show the wrong date format in Excel?

When downloading Google Sheets as Excel files, the original locale settings might not translate perfectly to Microsoft 365. This causes Excel to default to English (U.S.) or another region based on the document's hidden metadata or your browser's language settings at the time of download.

Does changing the Windows region affect all my Office applications?

Yes, changing your system's regional format in Windows Settings will update the default date, time, and currency formats across all Microsoft Office applications, including Word, Excel, and PowerPoint.

How do I remove an unexpected locale like Armenian from my Excel file?

You can override unexpected locales by selecting the affected cells, opening the Format Cells dialog (Ctrl+1), and manually changing the Locale (Location) setting under the Date or Time formats back to your preferred region, such as English (United Kingdom).
