EDI Viewer & X12 Viewer, EDIFACT Viewer for VS Code

Zovo Pro: USD 19 once, every Zovo tool

Open an X12 or EDIFACT file in VS Code and read it as a tree: interchanges, functional groups, transaction sets or messages, loops and segments, with the name of every element and the meaning of its codes. The viewer also checks control numbers, counts and mandatory elements. In the text editor you get colours, names on hover, problems in the Problems panel, and Format and Minify commands. No network, read-only.

EDI viewer: an X12 850 purchase order as a tree, with the elements of a PO1 line and their names

What you see

	X12	EDIFACT
Separators	read from the ISA header (element, repetition ISA11, component ISA16, segment terminator), with or without line breaks	read from UNA, or the defaults `:+.? '`; the release character `?` is honoured
Envelopes	ISA/IEA, GS/GE, ST/SE	UNB/UNZ, UNG/UNE, UNH/UNT
Loops	HL hierarchy (856, 837, 270, 271, 276, 277), NM1, N1, PO1, IT1, LIN, CLM, CLP, SVC, LX, S5 and more	segment groups: NAD, LIN, CPS, PAC, RFF, TDT, GID and more
Names	segments, elements and common code lists for 850, 855, 810, 856, 997, 999, 820, 837P, 837I, 835, 270, 271, 276, 277, 204, 214, 940, 945	segments, composites, components and code lists for ORDERS, ORDRSP, DESADV, INVOIC, IFTMIN, PRICAT, APERAK, CONTRL

Tree tab: click a segment to see each element with its ID (for example BEG03 or NAD 02-1), name, value and code meaning. Double-click (or Enter) selects the segment in the text editor next to the viewer; a click on an element row selects just that element.
Segments tab: every segment with its line number and data, with a filter by segment ID or text.
Problems tab: every problem with its line; a click shows the segment.
Names are short descriptions written for this extension. EDIFACT names follow the public UN/CEFACT directories.

What is checked

X12: the width of each ISA field, ISA13 against IEA02, GS06 against GE02, ST02 against SE02, the number of functional groups (IEA01), transaction sets (GE01) and segments (SE01).
EDIFACT: UNB05 against UNZ02, UNG05 against UNE02, UNH01 against UNT02, and the counts in UNZ01, UNE01 and UNT01.
Segments that are not part of the transaction set or message type, segments outside an envelope, missing trailers, a duplicate control number in one group.
Empty mandatory elements in the segments the dictionary knows.

Text editor

Files ending in .edi, .x12, .edifact, .edf, .850, .810, .856, .837, .835 and other transaction numbers open as EDI text; files that start with ISA, UNA or UNB are found by their first line too.
Hover: rest the mouse on a value to see its element ID, name and code meaning.
Problems: the same checks as the viewer, shown in VS Code's Problems panel while you type.
Format EDI (one segment per line) and Minify EDI (one line). Only the white space between segments changes; the segments stay byte for byte the same.

Free and Pro

Everything above is free, with no limit and no sign-in. Three Zovo Pro tools save time on bigger jobs. Each has 3 free tries on your computer, and a try counts only when the tool gives you a result.

Tool	Free	Zovo Pro
Tree, segments, problems, names, hover, format, minify	yes	yes
Export to JSON (a tree per transaction with element names) or CSV (line items of 850, 810, 856, ORDERS, INVOIC, DESADV; one row per segment for other types)	3 tries	yes
Compare two EDI files segment by segment: added, removed and changed segments with the elements that differ; can ignore control numbers, dates and times; Markdown report	3 tries	yes
Validate a folder: every X12 and EDIFACT file checked, one report with errors, warnings, counts and trading partners (ISA06/ISA08, UNB sender and recipient), as Markdown and CSV	3 tries	yes

Zovo Pro is USD 19 once and turns on the Pro tools in every Zovo extension. Nothing about Pro shows when you open a file; it only comes up when you click one of the three tools. To hide the buttons, set ediViewer.showProTools to false.

Safe with any file

The file is read in a separate worker thread with a time and memory limit. A broken or hostile file gives a message; it cannot freeze VS Code.
Files up to 64 MB open in the viewer; up to 500,000 segments are shown. Every value is shown as text, never as HTML.
Read-only: the viewer never writes to the file.
No network and no telemetry.
