What Is an X12 997 File?
The 997 (Functional Acknowledgment) is the ANSI X12 transaction set a trading partner sends back to confirm receipt of a functional group of EDI documents — and, critically, whether each transaction set inside it was accepted, accepted-with-errors, or rejected. It does not confirm business-level approval (that's a separate response like an 855 PO acknowledgment) — a 997 only confirms that the EDI envelope and syntax were readable. It's the first thing to check when a trading partner says "we never received your file" or "your file was rejected."

Why Convert a 997 to CSV?
997s are dense, code-driven files that are painful to read as raw text — a single rejected transaction set can be buried among dozens of AK segments. Converting to CSV surfaces every AK2 transaction set reference next to its AK5 accept/reject status in one scannable table, so you can immediately see which specific transaction(s) failed instead of manually counting segments.
Key Segments You'll See in a 997 Export
- AK1 — Functional Group Response Header: which functional group (e.g. all the 850s in a batch) this acknowledgment refers to.
- AK2 — Transaction Set Response Header: identifies one specific transaction set (e.g. a single 850) inside the group.
- AK3 / AK4 — Data Segment/Element Note: pinpoint exactly which segment and element caused a syntax error, when present.
- AK5 — Transaction Set Response Trailer: the accept/reject status code for that one transaction set (A = Accepted, E = Accepted with Errors, R = Rejected).
- AK9 — Functional Group Response Trailer: the overall accept/reject status for the whole group, plus counts of included, received, and accepted transaction sets.
What Do the AK5/AK9 Status Codes Mean?
The most common codes are A (Accepted), E (Accepted, But Errors Were Noted), and R (Rejected). An AK9 of "A" with AK5 codes of "A" throughout means everything in the batch was received cleanly. Any "R" means that specific transaction set must be corrected and resent — the AK3/AK4 segments (when present) tell you exactly which segment and element triggered the rejection.

Frequently Asked Questions
Does a 997 confirm my business document was approved?
No — a 997 only confirms the EDI file's syntax and envelope were received and readable. Business-level approval (e.g. of a purchase order) is a separate response, like an 855.
What does an AK5 code of "R" mean?
"R" means that specific transaction set was rejected. Check the accompanying AK3/AK4 segments if present — they identify the exact segment and element that caused the rejection.
Can one 997 acknowledge multiple transaction sets at once?
Yes — a single 997 can contain multiple AK2/AK5 pairs, one for each transaction set in the functional group being acknowledged.
Is my file uploaded anywhere?
No. Parsing happens entirely in your browser; the file is never transmitted to a server.
Is this a subscription?
No — a one-time payment (currently 50% off at $29.99) unlocks unlimited full-file exports, with no recurring fees.
Does this support both 4010 and 5010 versions, and can I batch-convert multiple files?
Yes on versions — the parser reads structurally from the file's own delimiters, so 4010, 5010, and other X12 versions of the 997 all work. It currently processes one file at a time; there's no bulk/batch upload feature yet. It runs on any device with a modern browser, including Mac and Chromebook.
