What Makes It Different

Every feature built for operations teams,
not just developers.

🗺

Live Source Tree

Paste or upload any X12 document and instantly see every parsed segment and field in a browsable tree. Click the + on any field to create a mapping rule with the source pre-filled.

No schema files needed

⚡

IF / AND / ELSE Logic

EDI qualifier pairs are natively supported. Build rules like "IF PO1.06 = IN → map PO1.07. AND PO1.02 ≠ 0. ELSE set value: N/A." Stack unlimited AND conditions per rule.

No code — just dropdowns

⚡

Quick-Start Templates

Pre-built maps for 850 Purchase Order, 856 Ship Notice, 810 Invoice, and JSON→850 reverse. Load one, tweak a few target field names, and you're converting in under a minute.

8 built-in templates

🔄

Bidirectional & All Formats

X12 → JSON, XML, or CSV. Or the reverse: JSON, CSV → X12 envelope. Switch direction in the toolbar. Every format works the same way — same rules, same logic.

X12 ↔ JSON / XML / CSV

💾

Save & Reuse Maps

Name your map and save it. Load any saved map in one click for future documents. Share maps across your team. Maps are versioned and tied to your account.

Unlimited saved maps

Document Vault

Every converted document is automatically saved to your vault with full audit history — original, output, map used, timestamp, and status. Filter, preview, and re-run any document.

7-year audit retention

Common Questions

FAQ

Do I need to know EDI to use the mapper?

Not deeply. If you know your target data structure (e.g. the JSON your ERP expects), you just need to match fields. The source tree shows you exactly what's in the X12 document, labeled by segment and element number.

Do I need a developer account to use the mapper?

Yes — the Visual Mapping GUI is a developer account feature. If you're a business (client), your EDI developer uses their developer account to configure the mappings. You then see the mapping status on your dashboard and activate each partner once the mapping is ready.

What X12 transaction sets are supported?

All standard X12 sets relevant to non-pharmaceutical industries — 850, 856, 810, 860, 204, 210, 214, 830, 862, and many more. Select your industry in the toolbar and the list filters automatically.

Can I convert JSON or CSV back to X12?

Yes. Set the direction to Outbound in the toolbar and the mapper works in reverse — your JSON or CSV fields become source, and your X12 segment.element addresses become the targets.

How does the IF/AND/ELSE logic work?

Each mapping rule can have an optional condition panel. Set the qualifier field, operator (equals, contains, starts with, is one of, etc.), and value. Add AND conditions to chain multiple checks. Set an ELSE to output a fixed value or map a different source field when the condition fails.

Are my saved maps private?

Yes. All maps and converted documents are scoped to your account and never shared with other organizations. Enterprise plans get dedicated infrastructure with no cross-tenant data storage.
