Word ↔ Number converter

Convert English number words to digits and digits to words. Useful for forms, invoices, and copy where you need both formats.

Word to number

English-only conversion using the short-scale system (thousand, million, billion, trillion). Supports negatives and decimals.
One thousand two hundred thirty-four
-45.67
1,523
Tip: For large numbers, use: thousand / million / billion / trillion. If something doesn’t parse, it’s usually due to unsupported words or ordering.

Use cases

Handy for finance/reporting copy (“one thousand five hundred…”) as well as form inputs where users might type either words or digits. It supports negatives and decimals for quick conversions.

How to use

  1. Pick a mode: Word → Number or Number → Word.
  2. Paste an example input (words like “one thousand…” or digits like “1,523”).
  3. Copy the result for your document or form.
