Number to Words Converter

A powerful tool that converts numbers into their word equivalents using a deterministic, grammar-aware engine. Unlike simple dictionary lookups, it properly handles each language's unique rules — such as Indonesian's "seratus" and "seribu" prefixes, or English hyphenation rules. Ideal for finance professionals, developers building localization features, check writing, and accessibility.
