FAQ
Frequently asked questions
Everything you need to know about number to words converter.
What is the largest number I can convert?
Up to 999,999,999,999 (12 digits). Larger inputs show the error 'Maximum supported value is 999,999,999,999' instead of producing an incorrect result.
How are decimal numbers written out?
Decimal parts support up to 2 places and are read digit by digit after 'point', so 12.5 becomes 'Twelve point five', following the convention used on checks and invoices.
Can I convert negative numbers?
Yes. A leading minus sign produces the word 'minus' before the words, so -42 renders as 'Minus forty-two'.
Are commas and spaces in my input a problem?
No. Commas and spaces are stripped automatically, so '1,234,567.89' and '1234567.89' both convert correctly to the same English words.
What is the output good for?
The capitalized result is ideal for checks, bank drafts, invoices, and formal documents where amounts must be written out in words to prevent fraud.
