Convert words into numbers

This tool converts words into numbers. It scans your input text for sequences of number words (e.g., "one", "two", "three million", "four hundred twenty five") and replaces them with their corresponding numeric digit representations. You can choose to convert: • All recognized number words. • Only those number words that match specified substrings. • All number words except those containing specified substrings. • Or display the converted number using a custom format. This robust conversion supports numbers up to quintillions. Simply enter your text, adjust the settings in the options below, and click the process button.
