How to Parse HL7 Messages

This tool converts raw HL7 v2.x messages (pipe‑delimited) into a clean, human‑readable format. It extracts patient information from PID, order details from ORC/OBR, and results from OBX.

Step 1 — Paste Your HL7 Message

Copy the raw HL7 message (each segment on a separate line) and paste it into the input box.

Step 2 — Choose Parse Options

Select which segments to parse: PID (patient), ORC/OBR (orders), OBX (results). You can also choose to format dates from YYYYMMDD to MM/DD/YYYY.

Step 3 — Get Readable Output

The parsed information appears instantly on the right. Copy it to your clipboard or download as a .txt file.

Frequently Asked Questions

What HL7 versions are supported?

This tool supports HL7 v2.x messages using the standard pipe (`|`) field separator and caret (`^`) component separator. It works with common segments like PID, ORC, OBR, and OBX.

Can it parse multi-line messages?

Yes. The tool expects one segment per line. It will combine related segments (e.g., OBR followed by OBX) into a coherent output.

How are names formatted?

Names in PID.5 (patient name) are expected in the format `Family^Given^Middle`. The output will be “Family, Given Middle”.

Is it safe for PHI?

Absolutely. All processing happens in your browser – no data is ever sent to a server. It’s 100% HIPAA‑safe.
