Number Formatter
Add thousands separators and set decimal places.
Readable numbers
Large numbers are hard to read without grouping, and different regions group them differently. This formatter adds the separator you choose and rounds to the decimal places you set.
The value 1234567.891 becomes 1,234,567.89 with comma grouping and two decimals. Switch to spaces or periods to match European conventions, or turn grouping off entirely.
Simple and private
The formatting runs in your browser, so nothing you enter is uploaded.
