Number to Words Converter

Each line of the input box is treated as a separate number, and the answer appears on the matching line as number → words.

1. Type or paste your numbers, one per line. Commas, spaces and currency signs such as $ or £ are ignored, so 1,234.56 is fine.
2. Choose Write as: Words, Ordinal or Money (cheque wording).
3. If you picked Money, set Currency for money to Dollars and cents, Pounds and pence, Euros and cents, or Rupees and paise.
4. Tick Use "and" after hundreds (British style) if you want 1,234 read as one thousand two hundred and thirty-four.
5. Copy the lines you need. A line that is not a number is skipped with a short message, and the others still convert.

Negative numbers start with the word minus. In Words mode the digits after a decimal point are read one at a time, so 3.14 becomes three point one four and 0.05 becomes zero point zero five. Money mode rounds to two decimal places, capitalises the first letter and ends with only when there are no cents. Ordinals need whole numbers.

The default output follows the American habit of leaving out and inside a number, so 1,234 is one thousand two hundred thirty-four. British writing normally puts and after the hundreds, giving one thousand two hundred and thirty-four, and also before a final group under one hundred, as in one thousand and five. The tick box switches between the two. Pick the one that matches your document, and keep to it throughout. Hyphens join tens and units from twenty-one to ninety-nine in both styles.

On a cheque, the amount in words is the line that settles any doubt when the figures are unclear. Wording conventions differ by country and bank, so check the rules for your own account before relying on a generated line. The tool gives a clean starting wording; it does not validate the cheque itself. If you also need totals worked out, the VAT and sales tax calculator and the tip calculator produce the figures you can paste in here.

People reach for this converter when drafting invoices and contracts, where an amount is written in both digits and words, when a style guide says to spell out numbers below ten or one hundred, when proofreading, and when teaching how number names are built.

• Whole numbers can have up to 36 digits, which reaches the decillions. Names beyond decillion are not available, and longer input is refused.
• The output is English only.
• Scientific notation such as 1e6 is not accepted. Write out the digits.
• Word counts of the finished text can be checked with the word counter.
• Only digits, an optional minus sign and one decimal point are read. Anything else on a line, such as a unit or a stray letter, causes that line to be skipped.

A few practical habits help. Convert the figure, then read the words back against the digits before you paste them anywhere. In Money mode, enter the exact amount you want written, because values with more than two decimals are rounded and the line says so. For long lists, paste them in a single batch: every line is converted independently, so a typo on one line never spoils the rest. Remember that the output is a draft of the wording, so proofread it before it goes into a contract or onto a cheque.
