Using Words to Numbers Converter
Convert English number words into exact digits, including negative values, decimals and large scales. Batch-convert lines and review errors individually.
- Paste English cardinal numbers, one per line, or open a UTF-8 text file.
- Choose plain digits or thousands separators, then convert. Invalid lines appear in the JSON report without blocking valid lines.
- Copy or download the valid values. Review the complete report before reusing batch output.
Example
English cardinal words, descending short-scale groups up to sextillion, and individual digits after “point”. This parser does not interpret currencies, ordinals, fractions or free-form sentences.
Questions & answers
Can it handle numbers beyond JavaScript’s safe integer range?
Yes. Whole-number groups use BigInt arithmetic, and decimal digits are retained as text. The tool does not round large integers through floating-point numbers.
Which number scales work?
English short-scale groups from thousand through sextillion. Groups must descend and cannot repeat. For example, one billion means 1,000,000,000.
How do I write a decimal?
Use point followed by individual digit words, such as one point zero five. Trailing decimal zeros are retained.
Can I convert a whole paragraph?
No. Enter one cardinal number per line, up to 200 lines. Ordinals, currency wording and ambiguous free-form prose are deliberately rejected.
Is my input uploaded for processing?
No processing upload is used. This tool runs in a local browser worker. Website ads and analytics follow the site privacy information.
