HL7v2 Parser

About the tool

HL7v2 messages are usually encoded in ER7 (Encoding Rules 7) which can be hard to understand, inspect, or edit.

This HL7v2 Parser allows you to quickly inspect ER7-encoded HL7v2 messages and view the detailed structure of each segment.

Get ready to explore some HL7v2!
