April 21, 2026 Major EDI v1.0

EDI Parser now available in Labs

Parse, inspect, and transform X12 EDI transactions directly in the browser — no setup, no server, no guesswork.

Highlights

  • Browser-native EDI parsing via WASM — works offline, nothing leaves your machine
  • Supports 834 benefit enrollment and 837 health care claim transactions
  • Clean JSON output: human-readable field names, no qualifier codes, no implementation noise
  • Interactive editor with live parse feedback and structured output panel

EDI is the backbone of healthcare data exchange, and it has always been painful to work with. Dense X12 syntax, numeric qualifier codes, nested segment loops — just reading a transaction takes expertise most teams don't have in-house.

The Josh EDI Parser is built for the people who have to deal with it every day. Paste any 834 or 837 transaction and get back clean, structured JSON. Field names are human-readable. Dates are named for what they mean. Code descriptions replace the codes themselves. It looks like JSON you would have written by hand, because that's the point.

The parser runs entirely in your browser via WebAssembly. Nothing is sent to a server. Nothing is logged. Your data stays yours.

Try it in Labs.
