achBldr is a NodeJS library for creating and manipulating ACH files (NACHA format).
This project is just getting started, but hopefully it will be production ready in a couple months (end Q2'19).
Planned features:
- Creation of ACH files in NACHA format (PPD, CCD, CTX to start) using high-level API (started)
- Ability to add addenda info consistent to entries (started)
- Parsing of ACH files into JSON (not started)
- Validation of existing ACH files and JSON fields (not started)
