Why this HL7 validator is safer for healthcare teams
Many online HL7 tools send message content to a backend for parsing. That model is a poor fit for environments where pasted samples can still contain patient identifiers. This validator keeps parsing and rule evaluation entirely inside the browser, so your raw HL7 text stays on the device where you opened the page.
The current validator checks common HL7 v2 structural rules derived from segment definitions for MSH, EVN, PID, PV1, ORC, OBR, and OBX, plus message-level checks for ADT, ORM, and ORU workflows. It also surfaces profile-sensitive checks such as the US Core inpatient PV1 location requirement.
