Use the DOCADV spec in your code

ediFabric .NET

Add the C# template and its common files to your project, or reference the template NuGet package, and read DOCADV files into TSDOCADV objects. See ediFabric .NET.

ediFabric Native

Native supports X12 today, and EDIFACT is coming. When it's available, map version D16A to this Native model with set_map to parse DOCADV files to JSON from Python, Java, C or C#. See ediFabric Native.

OpenEDI

Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.

Generate DOCADV classes in Python, Java, Node.js, Go, Rust or C

The OpenEDI file describes each DOCADV as JSON. To work with DOCADV data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSDOCADV. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
