Hi Thomas,
If you would have a table with the words next to the number, you could look it up. But the big question is: how would you fill a table like that without manually entering every single value?
When you Google on “How to convert numbers to Words” you will find a lot of online solutions. They seem to derive their results from a formula.
When you look for a solution in Excel, Microsoft Support will tell you that there is no instant solution, but you can achieve it by writing VBA code. Here is a link that will show you how to do that.

After you get the results, you can paste them in Airtable in a table.
