Add your EDI file
Drop one or more .edi files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
EDI to JSON
Converting a .edi font to .json repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .edi font to .json repackages the same glyphs and metrics for a different delivery target. A .edi file is an electronic data interchange document — a business record such as a purchase order, invoice or shipping notice, encoded as delimited segments for machine-to-machine exchange. The extension itself is ambiguous: it is used by both ANSI ASC X12, the North American standard, and UN/EDIFACT, the international one. The two are different formats, and you can tell them apart from the first three bytes.
A .json file holds JavaScript Object Notation: nested objects, arrays, strings, numbers, booleans, and null written in a strict text syntax. It is the default data language of the web — most APIs speak nothing else. For this route the practical draw is parsers ship in the standard library of essentially every language and readable by humans and machines alike — balanced against no comments — a perpetual annoyance for configuration files, which is worth knowing before you commit a large batch.
Why convert EDI to JSON?
The practical trigger for this conversion is usually a mismatch: with .edi, names a family, not a format — a .edi file may be X12, EDIFACT, TRADACOMS or a partner's own dialect. Switching to .json buys you parsers ship in the standard library of essentially every language, which is why it is the better fit for rEST and HTTP API request and response payloads. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
EDI vs JSON at a glance
| Aspect | EDI interchange (.edi) (.edi) | JSON data (.json) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | aSC X12 interchanges begin with a fixed-width ISA envelope; UN/EDIFACT interchanges begin with an optional UNA service string advice followed by UNB | exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate |
| Strongest at | opening a .edi file a trading partner sent when you do not know which standard it uses | rEST and HTTP API request and response payloads |
| Weak spot | names a family, not a format — a .edi file may be X12, EDIFACT, TRADACOMS or a partner's own dialect | no comments — a perpetual annoyance for configuration files |
Pick JSON as the output
Select .json in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JSON is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JSON file. Outputs keep the original filename with the .json extension.
EDI to JSON questions, answered
Will converting EDI to JSON lose quality?
There is no visual quality to lose — edi is text-oriented and json is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert EDI files here?
Yes — the .edi file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the JSON file work?
Browsers parse it natively through JSON.parse, every mainstream language bundles support, and most editors validate and highlight it out of the box. Viewing a raw .json file is possible in any text editor or browser tab.
Will the JSON file be bigger or smaller than my EDI?
It depends on the content: exactly six value types; no dates, no comments, no trailing commas — the strictness is deliberate. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my EDI file?
In .edi, envelope metadata is preserved for both standards: sender and receiver identifiers, date and time, version and control numbers, plus X12's usage indicator and EDIFACT's declared delimiters. Implementation guidelines, message directories and code lists are not interpreted; raw element values are carried through unchanged, with EDIFACT composites split on the component separator. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
