Quick EDI tools
Three small helpers for the “what am I looking at?” moment.
These are quick browser-only checks for common EDI triage. Paste a small snippet, run the helper, and use the result as a plain-English starting point.
01
Document type identifier
Find the transaction set
Paste a few X12 lines and it will look for ST, GS, and familiar starting segments like BEG, BSN, BIG, BIA, and BAK.
Waiting for a snippet.
Paste one or two segments and run the identifier.
02
997 explainer
Read the acknowledgement
Paste a 997 and get the big answer first: accepted, rejected, accepted with errors, or partially accepted.
Waiting for a 997.
Paste the acknowledgement and run the explainer.
03
856 ASN structure checker
Make HL loops readable
Paste an ASN and it will summarize the shipment/order/pack/item hierarchy so the shape is easier to reason about.
Waiting for an ASN.
Paste an 856 snippet and run the checker.

Syncora focuses on the practical loop: orders come in, warehouse state moves with the shipment, outbound documents go back, and exceptions stay visible.
The buyer says what they want, where it goes, and how it should be packed or priced.
The supplier confirms, rejects, or changes order lines before fulfillment starts.
The shipment story: cartons, tracking, quantities, dates, and what is inside each package.
Current inventory position, available-to-ship balances, and location-level stock updates.
The billing document that ties shipped goods, charges, allowances, and totals together.
A receipt that says whether the receiver accepted the document structure.
