HL7 Editor Free

About This Tool

The HL7 Editor Free is a domain-focused tool for developers and systems integrators who work with HL7 v2 messages. It provides parsing, validation, editing, and transformation capabilities to support healthcare interoperability testing, interface development, and vendor certification without licensing costs.
Conceptually, the tool tokenizes HL7 messages into segments, decodes field separators and encoding characters from MSH, and applies a dictionary of segment definitions. It can produce a structured JSON representation, reassemble valid HL7 messages from edited components, serialize to XML, and generate ACKs for testing interoperability workflows.
Key differentiators include a free, zero-cost workflow for both offline and online deployments, version-aware validation (2.3–2.8), and export options to HL7, JSON, XML, or CSV. Templates for common messages speed integration, while a pluggable segment dictionary supports local deployments.
It provides comprehensive error reporting with segment-level details and field positions, supports constraints on required segments, field lengths, and prohibited characters, and can export to multiple formats for use in test harnesses and CI pipelines. Excludes HL7 v3 and FHIR, focusing on the widely deployed v2 ecosystem and vendor interoperability.
