How it works

Do you need to fill in a check, a contract or a notarized deed and write an amount in words to prevent any alteration of the figure? Enter the whole number, click "Convert" and instantly get its spelled-out form in French, ready to copy.

Which numbers are supported?

Whole numbers from -999,999 to 999,999 (positive or negative). Decimal numbers and values of a million or more are not yet supported.

Are French grammar agreement rules respected?

Yes: the tool applies the classic agreement rules, such as "quatre-vingts" (with an s) but "quatre-vingt-un" (without an s), or "deux cents" but "deux cent un", as well as the "et" in "vingt et un", "soixante et onze", etc.
