A converter that stays on your machine

Humanising Technologies builds custom software for health software businesses. This tool is free because anyone using it already has an interoperability problem in flight.

What this converts

Output is a FHIR R4 transaction Bundle. Field mappings follow the HL7 v2-to-FHIR Implementation Guide.

Every family in the picker is a first-class conversion. The same identifier, SN, ED, timezone and drop-report rules apply across ADT, results, orders, pharmacy, scheduling, documents, financial, problems and control messages.

  • ADT A01, A02, A03, A04, A05, A08, A40 (and other ADT events that reuse these segments)
  • ORU results, including SN, ED, TX repeats and withdrawn PID-2 / PID-4 identifiers
  • ADT A08 with a non-standard MRG, PID-7 birth time, and interpreter ZPD
  • ORM / OML / REF orders
  • RDE / RAS / RDS / VXU pharmacy and immunisation
  • SIU scheduling (book and cancel), MDM documents
  • DFT / BAR financial, PPR problems
  • ACK (accept and reject) and QBP control messages
  • Segments: MSH, EVN, PID, PD1, NK1, PV1, PV2, AL1, IAM, DG1, PRB, ACC, IN1, IN2, PR1, PRT, ROL, PRD, ORC, OBR, OBX, SPM, NTE, RXO, RXE, RXC, RXA, RXD, RXR, SCH, ARQ, RGS, AIS, AIL, AIP, AIG, TXA, FT1, GT1, TQ1, RF1, MRG, MSA, QPD, RCP

Cousin trigger events convert when they use the same segments. CDA / C-CDA is a different standard and is not converted here. Site Z-segments still become placeholder Basic resources.

Privacy

Conversion is entirely client-side. There is no upload endpoint. We do not put message content in analytics, error reports or URLs. Lead forms send only your name, work email, a note, the message type and whether unmapped segments were present.

You can prove it: open DevTools, Network tab, paste a message, and watch. Nothing leaves.

Accuracy

Wrong output is worse than no tool. The mapper is narrow on purpose. If a field has no standard FHIR target it is listed in the conversion report rather than guessed. Z-segments become placeholder Basic resources with an extension — useful, not a clinical mapping.

Not for clinical use. Review output before production use. No warranty.

When a generic mapper is not enough

Real feeds have Z-segments and site-specific quirks. That is the normal case, and it is what we get hired for. If you want this as an API, a custom mapping, or a pipeline into your FHIR store, write to info@humn.au or call 1300 285 769.

Better tools for some jobs

Microsoft's FHIR-Converter is free, open source, and stronger than a browser mapper once you can clone a repo and learn Liquid templates. Use it when you need that depth. Use this when you need an answer now, on this machine.
