You need to fill in a check for 3,450.75, write a rental receipt or a contract where the law requires the amount in words. One misspelled "four hundred fifty" or a stray "and" and the bank bounces the check or the contract is open to doubt.

Writing the amount in words without mistakes: the part of a check nobody should improvise
On a check, a promissory note or a contract, the amount in words usually prevails over the figure if the two disagree. A misplaced hyphen or an extra "and" is not a detail: it can void the document or start a dispute.
The converter applies each language's rules: Spanish elision («veintiún mil»), English hyphens («thirty-four») and the Portuguese «e» between groups («mil duzentos e trinta e quatro»). Cents come out as a fraction (56/100) in Spanish and English and in words in Portuguese.

- •Accepts decimal point or comma formats (1,234.56 and 1.234,56).
