Add Commas to Numbers

Use this tool to add commas or periods to numbers in a text. It works by extracting numbers and then applying commas/periods where they are applicable. As a general rule when writing figures, any numbers with more than three digits will have a comma after every third digit (reading from right to left).

The tool assumes that the numbers in the text are unformatted but it can detect decimal separators and the fractional part of the number (e.g. 1000.00). Once you applied commas, you cannot use them again to apply periods (for European languages). To revert the changes, use the “Undo” function under the Edit button.

In US/UK English, the comma is used to separate every third digit and the period is used as a decimal separator. This is the default setting.

1000
1000.00
10000

1,000
1,000.00
10,000

In many European countries, it is the other way around. The period is used as the thousands separator and the comma is in place of the decimal point. Use this option for other languages.
