EDI Studio parses, validates, and edits X12 EDI files with a structured tree view, smart error grouping, and in-place editing, so you can troubleshoot thousands of segments in minutes, not hours.
If you've ever opened a 5 MB X12 file in Notepad at midnight, you know exactly what we mean.
Traditional tools flood you with individual error lines. One bad N9 loop becomes 1,400 separate entries you have to scroll through by hand.
Files with no line breaks or whitespace are a wall of text. Understanding the hierarchy means memorizing segment positions by hand.
Fixing a value means hand-editing raw EDI, hoping you don't break a delimiter, then re-uploading to validate from scratch.
EDI Studio is built for the people who deal with EDI every day: 3PL ops teams, EDI analysts, supply-chain developers, and retail compliance coordinators.
Every file opens into a collapsible hierarchy you can navigate like a folder structure, no matter how the file was formatted.
Hundreds of errors of the same kind collapse into one row with a count. Expand to see details, or skip past them, your call.
Double-click any value to edit it inline. Code fields show a dropdown of valid options. No more typing into a wall of raw text.
Hover any field to see what it means, whether it's required, and what values are allowed. No more cross-referencing PDF specs.
Search the whole file by ID, value, or reference number. Click any result to jump straight to that row in the tree.
Validation for all supported transaction sets, with clear explanations of what's wrong, not just error codes.
Right-click any row to insert or remove. Critical structural rows are protected so you don't break a valid file.
Save changes back to the original file or export to JSON for downstream use. Formatting is preserved.
EDI Studio ships with full schema support for the nine most common X12 transaction sets used in retail and third-party logistics.
Whether you're debugging a retailer compliance failure at midnight or onboarding a new trading partner, EDI Studio has you covered.
Validate 940/943/944/945 flows before they hit your WMS. Catch bad lot data and SSCC problems at the door.
Stop scrolling raw text. See structure instantly, group errors intelligently, and fix values without breaking delimiters.
Inspect payloads while building integrations. Export clean JSON for your pipeline without writing a parser.
Verify ASNs against retailer requirements before they ship, and avoid the chargebacks that follow bad 856s.
Purpose-built for the way teams work today, with capabilities legacy tools simply don't have.
