Add Commas to Numbers


About


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 it again to apply periods (for European languages). To revert the changes, use the undo fuction under edit button.

Use comma


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

Use period


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