Parse a raw UN/EDIFACT interchange into structured JSON: UNA-declared separators, UNB/UNZ envelope, one entry per UNH/UNT message with decomposed segments (composite and simple elements), message type recognition (ORDERS, DESADV, INVOIC, ORDRSP...) and UNT/UNZ counter verification. Returns issues with segment, position, expected and found values.

Parse a raw ANSI X12 interchange into structured JSON. Delimiters are deduced from the ISA segment itself (element separator = 4th character, component separator = ISA16, segment terminator = the character after ISA16). Returns the ISA/GS/ST hierarchy with decomposed segments, transaction type recognition (850, 856, 810, 997...) and SE/GE/IEA counter and control-number verification.

Parse a cXML e-procurement document (PunchOutSetupRequest, PunchOutSetupResponse, OrderRequest) into structured JSON: From/To/Sender credentials, punchout session data, order header with totals and addresses, and line items with quantities and prices. SharedSecret values are detected but never echoed.

Detect the EDI standard (EDIFACT, X12 or cXML), verify the envelope structure, the mandatory segments for the recognized message type, and all control counters. Returns an actionable list of errors and warnings — each with segment, position, expected and found — plus a one-line summary.

Explain an EDI segment tag in plain English: role, key elements and a realistic example. Covers 35 EDIFACT segments (UNB, BGM, DTM, NAD, LIN, QTY...) and 28 X12 segments (ISA, ST, BEG, N1, PO1, HL...). Tags that exist in both standards (DTM, LIN) return both entries unless a standard is specified.

Generate a syntactically valid EDIFACT ORDERS D.96A interchange (UNA + UNB...UNZ) from a simple JSON order description: parties, dates, currency and line items. Envelopes, escaping and UNT/UNZ counters are computed automatically; the output round-trips through parse_edifact with zero issues.
