How to Change Excel from Indian to Western Thousands Separators
Product
Microsoft Excel
Device & OS
Windows
Scenario
Displaying large numbers and financial data in Excel using the Western thousands separator instead of the Indian format.
Observed behavior
Excel displays numbers as 10,00,000.00 based on Windows regional settings, and standard cell number formats alone cannot reliably override this global behavior.
Before you start

Save and close any active Excel workbooks before proceeding. Modifying system-wide regional settings requires Excel to be restarted to properly register the new thousands separator.

Solution 1Recommended

Modify Windows Regional Digit Grouping Settings

Adjust your system's Control Panel region settings to enforce the Western digit grouping globally across Windows and Excel.

Because Excel inherits its default number formatting directly from your computer's operating system, changing the Windows regional settings is the most reliable way to permanently switch from the Indian numbering system to the Western format.

1
Open the Windows Run Dialog

Press the Windows key + R on your keyboard simultaneously to open the Run command window.

2
Access Regional Settings

Type 'control international' into the text box and press Enter to open the Region settings panel.

3
Open Additional Settings

At the bottom of the Region window, click on the 'Additional settings...' button to customize your data formats.

4
Modify Digit Grouping

Under the 'Numbers' tab, locate the 'Digit grouping' dropdown menu and select the Western format (123,456,789) instead of the Indian format.

5
Update Currency Format

Switch to the 'Currency' tab at the top of the window, apply the exact same digit grouping choice from the dropdown, and click OK to save your changes.

6
Restart Microsoft Excel

Reopen your Excel workbook. Your numbers will now automatically display using the Western thousands separator.

Frequently Asked Questions

Why does Excel show Indian numbering (lakhs and crores) instead of millions?

Excel automatically inherits your computer's Windows Regional Settings for displaying numbers, dates, and times. If your system locale is set to India, Excel defaults to the Indian digit grouping system (e.g., 10,00,000) rather than the Western system.

Can I change the thousands separator for just one specific Excel file?

Yes. While changing Windows settings affects all files, you can override the format for a specific file by highlighting the cells, opening Format Cells (Ctrl + 1), and applying a custom number format with a locale code, such as '[$-en-US]#,##0.00'.

Does changing Windows regional settings affect other applications?

Yes, modifying the digit grouping in the Windows Control Panel will apply the Western thousands separator globally. This means other programs that utilize system region settings, including web browsers, accounting software, and other Office applications, will also update their number formatting.
