Conversion between Payments Model and Nacha format

Hello, Is there documentation available about how to convert a Payments model to a Nacha formatted file?

While we do not have a document that specifically maps between the API and the Nacha file formats, if you look in the test documentation ( in the field name column on the far left, you will see the name of the Nacha file field in brackets in each of the API fields.  Our members also have access to the ISO mapping, which maps the data elements of the API from “English” business requirements to ISO 20022.
