Any number to words

A string based number to words converter. It can convert from very small to large decimal numbers(just for fun 🌈).

See Live Demo


npm i any-number-to-words



ES6 module format:

import {Converter} from "any-number-to-words";
const converter = new Converter();

CommonJS module format:

const {Converter} = require("any-number-to-words");
const converter = new Converter();

The default locale is enUS(English). To convert in to other locales(eg. bnBD) you also need to import or require the locales:

// bnBD is for Bengali
import {Converter, bnBD} from "any-number-to-words";
const converter = new Converter(bnBD);


const {Converter, bnBD} = require("any-number-to-words");
const converter = new Converter(bnBD);

Meat of the matter


converter.toWords(number|string, [options]);
  • 1st parameter(number|string): It can be a JavaScript number or a string. If it is a string it should follow the same syntax as JavaScript decimal number.
  • 2nd parameter([options|locale], optional): It is used to provide optional settings like comma separator: {comma: true}. However it can be used to override the whole locale. Or it can given some locale too to use that local temporarily.


// --- assuming the locale is enUS ---

converter.toWords(1729);                // → one thousand seven hundred twenty-nine 

// turn on commas
converter.toWords(1729, {comma: true}); // → one thousand, seven hundred twenty-nine

// string as input
converter.toWords('1729');              // → one thousand, seven hundred twenty-nine

// You can also use exponent notation
converter.toWords('1729e100');          // → seventeen tretrigintillion twenty-nine googol

That's basically it. Have fun!
