Currency are automatically formatted based on your locale settings you choose in Typeflow.us. Choose it carefully to make sure it matches your need.
Automatically, numbers will have basic formatting. So all numbers will look like that: 20000.00.
If you want to apply formatting, you need to apply locale settings.
In my screenshot above, my locale setting is French.
If I apply a locale format to a number, then the number will look like to French format. If I don't activate that, it will look like 123456789.
