How to Standardize Excel Date and Number Formats Across Languages
Question details
The user needs to display and input dates and numbers in a specific regional format (like German) while keeping the Excel application interface in English.
- Product
- Excel
- Device & OS
- Windows
- Scenario
- Entering dates and numbers into an English Excel installation, but requiring the display and decimal separators to follow German conventions.
- Observed behavior
- Excel automatically changes the input to match the system's regional settings instead of a worksheet-specific language, resulting in incorrect date separators (slashes instead of dots) and decimal marks (dots instead of commas).
Verify if the formatting issue occurs in all workbooks or just a specific shared file, as cell-specific custom formatting can override system default settings.
Adjust System Regional Format Settings
Since Excel relies on your operating system for default date and number formats, changing the Windows regional settings is the most comprehensive solution.
Excel does not have a read-write worksheet language setting. Instead, it derives default date input and numerical formatting entirely from Windows system and regional settings.
By modifying the system region to your target language (e.g., German), Excel will automatically recognize and format dates with dots and decimals with commas, regardless of the Excel UI language.
Click the Windows Start menu, type 'Control Panel', and press Enter to open it.
Click on 'Clock and Region', then select 'Region' to open the settings dialog.
Under the 'Formats' tab, click the 'Format' dropdown menu and select your desired language region (e.g., 'German (Germany)').
Click 'Apply' and then 'OK'. Restart Excel for the new system default formats to take effect.
Override Decimal and Thousands Separators in Excel Options
If you only need to change how decimal points and thousands separators behave without altering system settings, you can modify Excel's advanced options.
Apply Custom Cell Formatting
Use this method if you cannot change your system settings but need specific cells to display dates in a foreign format (like DD.MM.YYYY).
Easily Apply Custom Regional Formats with WPS Spreadsheet
WPS Spreadsheet is a powerful, highly compatible tool that allows you to seamlessly apply and manage diverse regional date and number formats directly within your workbook, bypassing complex system-wide changes.

- 3. Open Format Cells dialog: Right-click the selected area and choose 'Format Cells', or press the Ctrl+1 shortcut.
- 4. Apply custom locale settings: Navigate to the 'Number' tab, select 'Date', and choose your preferred locale from the 'Locale (Location)' dropdown to instantly apply the correct formatting.
Frequently Asked Questions
Can I set a specific language for just one Excel worksheet?
No, Excel does not have a worksheet-specific language setting for data input. It derives its default date and number formatting directly from your operating system's regional settings. To fix formatting for a single sheet, you must apply explicit custom cell formats.
Why do my dates appear with slashes (15/12/2021) instead of dots (15.12.2021)?
This happens because your Windows regional format is set to a locale that defaults to slashes (like English). You can change this by updating your system region to German in the Windows Control Panel, or by applying a custom 'DD.MM.YYYY' format to the specific cells.
How can I type a comma as a decimal separator in an English Excel installation?
You can override the system default directly within Excel. Go to File > Options > Advanced, uncheck 'Use system separators', and manually set the 'Decimal separator' to a comma (,).
Will changing my Windows regional settings affect other applications?
Yes, modifying the Windows regional format will change how dates, times, and currencies are displayed universally across all programs installed on your computer, not just Excel.
