Type a number, pick language and format. Output updates live. For currency, the integer part is dollars (or whatever) and the decimal is cents.

Spelling numbers out in words

Some documents need a number written out, not just as digits. Cheques require the amount in words as a fraud check; contracts and invoices often spell a figure alongside its numerals; and written-out numbers can read more naturally in certain accessible text.

This converts a number to its spelled-out form in English, Spanish, French, or German, across four formats: cardinal (one hundred), ordinal (first), currency, and US cheque style (ONE HUNDRED AND 50/100). The reverse — parsing words back into a number — is words to number; to reformat with locale separators or scientific notation instead, the number format converter.

Common use cases

  • Cheque writing — get the amount in words for the “pay to the order of” line.
  • Invoices and contracts — spell a figure out alongside its numerals.
  • Accessibility — produce screen-reader-friendly number text.
  • Localization — render a number in Spanish, French, or German words.
  • Verification — double-check a number by reading its written form.

Frequently asked questions

Which languages are supported?

English, Spanish, French, and German.

What is “US check format”?

The cheque convention: words for the dollars plus an NN/100 fraction for the cents, for example ONE HUNDRED AND 50/100.

Can it produce ordinals?

Yes. The ordinal format gives “first”, “second”, and so on rather than “one”, “two”.

How do I go from words back to a number?

Use words to number, which parses spelled-out English numbers into digits.
