Frequently Asked Questions

How large a number converts?

Up to billions: 1,250,000 becomes 'one million two hundred fifty thousand'. Beyond billions, split into parts — everyday contracts never need more.

Check writing: which format?

Title case with 'and' per your bank's convention ('one thousand two hundred and fifty'). Confirm the bank's exact wording rules for large checks.

Does it handle decimals?

Yes — paise/cents render as fractions or point-words per setting. Financial documents usually want 'point' style spelled out.

Is my number uploaded?

No — conversion runs locally in your browser. Nothing leaves your device.
