Field mapping table: which EDI segment fills which column (for IT & bookkeepers)

ANSI X12 Envelope & Core Segment Decoding Matrix

Deterministic segment-to-column mapping rules enforced by our client-side X12 engine

Source X12 Segment / Element	Sample Raw Value	Target ERP / CSV Column	Transformation & Validation Logic
ISA06 / ISA08	925485US00 / 5551234567	Sender / Receiver ID	Extracts 15-char padded trading partner IDs and dynamic delimiters at bytes 3, 82, 104, 105.
BEG03 / BIG02 / BSN02	4500991288	Document Number	Identifies primary PO Number (850), Invoice Number (810), or Shipment ID (856).
PO106..PO115	UP012345678905IN*554433221	Normalized Product IDs	Sliding 2-element window resolves UPC (UP), Buyer Item/DPCI (IN/BP), and Vendor SKU (VN).

Critical Chargeback & Import Pitfalls We Prevent

Common EDI mistakes that trigger $250+ retailer fines or accounting balance errors

80-Column Mainframe Hard Line Wraps

Risk: Parser Crash / Corrupted SKUs

Legacy retail VANs often wrap X12 streams at column 80 with CRLF, splitting PO1 or ISA segments in half.

Our streaming parser strips non-terminator CR/LF characters before splitting elements.

Custom Non-Standard Delimiters

Risk: 997 Rejection

Assuming * and ~ are universal fails when partners use |, ^, or >.

Always inspect ISA index 3 (element), index 104 (component), and index 105 (segment).

Unbalanced SE01 After Manual Notepad Edits

Risk: $200+ Admin Fee

Adding or removing a REF or DTM line in a text editor without updating SE01 triggers an immediate 997 rejection.

Use the 1-Click Auto-Fix button to recalculate SE01 and CTT01 automatically.

Frequently Asked Technical Questions

ANSI X12 specification details, retail companion rules, and ERP import answers

Is my confidential wholesale pricing uploaded to a server?

No. EDIParse runs 100% inside your browser using a client-side TypeScript engine. Your .edi files never leave your computer.

Does the viewer support multi-ST batch files?

Yes. If an ISA/GS envelope contains 50 store Purchase Orders, you can switch between individual ST transactions or export them all into a single consolidated sheet.
