Why Convert EDI to JSON?
JSON is the native data format of nearly every modern API, scripting language, and integration platform. If you're writing a script to check test EDI files, feeding parsed data into a webhook, or building a custom dashboard, JSON is usually a more direct fit than CSV or Excel — no delimiter parsing, no spreadsheet library, just JSON.parse() and you have a native array of objects.

The JSON Output Structure
The exported JSON is a flat array — one object per parsed data element — using the same field names and ordering as the CSV and Excel exports, so scripts consuming any of the three formats stay consistent:
[
{
"group": 3,
"segmentId": "CLM",
"segmentDescription": "Claim Information",
"elementPosition": "1",
"value": "CLAIM0001"
},
{
"group": 3,
"segmentId": "CLM",
"segmentDescription": "Claim Information",
"elementPosition": "2",
"value": "250.00"
}
]
This "long" format (one row per element, rather than one nested object per document) is deliberate — it stays consistent no matter which transaction set or standard you're parsing, and it's trivial to re-shape in code (e.g. array.filter() and .reduce() in JavaScript, or a quick pandas groupby in Python) into whatever nested shape your specific downstream system expects.
Common Developer Use Cases
- Integration testing — quickly turn a trading partner's sample EDI file into JSON test fixtures for unit tests, without writing your own parser first.
- Webhook payload construction — reshape the flat array into the specific JSON schema your receiving API expects.
- Ad-hoc scripting — pull a JSON export into a Python or Node.js script for quick analysis (e.g. summing claim totals, counting line items) without hand-writing an X12/EDIFACT tokenizer.
- Documentation and support — attach a readable JSON snippet to a support ticket or bug report describing exactly what a trading partner's file contains, in a format any developer can read at a glance.
CSV vs. JSON: Which Should You Export?
If a human is going to open the file directly in Excel or Google Sheets, export CSV or Excel. If the data is headed into a script, an API call, or another program, JSON avoids an unnecessary parsing step. See EDI to CSV vs EDI to JSON: When to Use Each Format for a fuller comparison.
Also Known As
People also search for this as an "EDI json convertor," "X-12 to json," or land here after typing "edi file won't open" — all describe the same task this tool handles.
Is This a Real EDI API?
No — to be clear about scope, this is a browser-based conversion tool, not a hosted API endpoint you can call programmatically. If your workflow needs server-side, automated EDI-to-JSON conversion at scale (rather than an occasional manual file check), you'll want a dedicated EDI integration platform or a custom parser built around a library like this project's open parsing logic. This tool is aimed at manual inspection, one-off conversions, and test-fixture generation — not production, automated B2B pipelines.
Frequently Asked Questions
What does the JSON output look like?
A flat array of objects, one per parsed data element, with fields group, segmentId, segmentDescription, elementPosition, and value — the same field set used in the CSV/Excel exports.
Is this a hosted API I can call from my own code?
No, this is a browser-based tool for manual/ad-hoc conversion, not a callable API endpoint. See the section above for the distinction.
Is my EDI file uploaded anywhere?
No. Parsing and JSON generation both happen locally in your browser. Nothing is sent to a server.
Is this a subscription?
No — a one-time payment (currently 50% off at $29.99) unlocks unlimited full-file JSON exports on this browser, with no recurring fees.
Does this work on Mac, iPhone, or Chromebook, and can I convert multiple files at once?
Yes on device — it runs in any modern browser on Windows, Mac, Chromebook, or iPad, with no software to install. It currently handles one file at a time; there's no bulk/batch upload feature yet.
Does this convert EDI to XML instead of JSON?
Yes — Export to XML sits next to the JSON button. The two differ in shape: JSON export is a flat array of row objects that's easy to iterate, while the XML export is nested, with each <Segment> carrying its ID and description as attributes and its elements as children. Choose XML if your downstream system consumes documents; JSON if it consumes records.
