Number to Words
Spell numbers out in words, cheque-style.
Numbers written in words
Writing a number in words is what a cheque or contract needs so the amount cannot be altered: 1,234 becomes 'one thousand two hundred thirty-four'. This spells any integer out instantly.
Beyond cheques, it helps with invoices, legal documents, and any place a written amount must accompany the figures so a stray digit cannot quietly change the total.
Where it helps
It also catches transcription errors, since a wrong digit reads obviously wrong in words. Everything runs in your browser and nothing is uploaded.
