What Is the Add Commas to Numbers Tool?
The Add Commas to Numbers tool finds every number in a block of text and reformats it with the correct thousands separator for your locale. Six modes cover US standard (comma), European (dot), Indian lakh system, Swiss apostrophe, currency with dollar sign, and comma-removal. Paste a spreadsheet export, financial report, or any text with raw numbers — the tool updates them all instantly.
How to Use the Add Commas to Numbers Tool
- Paste your text with raw numbers (e.g.,
1234567.89) into the input box. - Choose a formatting mode — Standard (US) for most English content, European for German/French/Spanish reports.
- Check the stats — see how many numbers were found in your text.
- Copy or Download the reformatted text.

Number Formats at a Glance
| Mode | Input | Output |
|---|---|---|
| Standard (US) | 1234567.89 | 1,234,567.89 |
| European | 1234567.89 | 1.234.567,89 |
| Indian | 1234567 | 12,34,567 |

| Currency ($) | 1234.5 | $1,234.50 |
Best Practices and Limitations
Always use Remove Commas mode before parsing numbers in code or SQL — comma-formatted numbers will cause parse errors in most programming languages. When working with currency, use the Currency ($) mode to ensure exactly two decimal places appear consistently.
Limitations: The number detection regex matches sequences of digits with optional commas, apostrophes, and dots. It may not correctly parse European-formatted input (e.g., 1.234,56) — for best results, paste raw unformatted numbers. Very large numbers beyond JavaScript's safe integer limit (Number.MAX_SAFE_INTEGER) may lose precision during formatting.
