Chris Harvey, Bank of Bermuda

Convert Number to Words, including currency terms.

Sample Input:
Sample Output:
Sixty One Thousand Nine Hundred Fifteen Dollars and Twenty One Cents

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


This should work for most currencies, or even other units such as gallons or litres, etc. Give a null value for Currency if you don't want one. If you want the decimal part to be ignored, set Decimalcurr to "None".
In it's current form this function will handle values into the Trillions. As it works recursively, you can change the Out of Range check value and the names in one Choose function to extend it. It can also handle British Billions by changing the one Choose list.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

You need FileMaker Pro Advanced to create a new custom function called NumberInWords with the parameters: "NumberIn"; "Currency"; and "DecimalCurr"; and the calculation as above.

Then you can create a new calculation field as text in your invoice/sales orders table with the calculation:
NumberInWords ( YOURNUMBERFIELD ; "pounds" ; "pence" )

Change the YOURNUMBERFIELD text to the field name where your number you want to convert is.

Thanks so much for this custom function, Chris—works super!

Just one minor edit: the text "Four" has an added space at the end of the word (as written "Four "). Just removed that space in two places and now result has no double spacing.
