How do I write a check amount in words?

Write the whole-dollar portion in words followed by "and xx/100" for the cents. For example, 1,234.56 becomes "One thousand two hundred thirty-four and 56/100".

Does it handle large numbers?

Yes, the converter supports numbers up to billions and beyond, correctly inserting thousand, million, billion, and trillion place names as needed.
