Common Questions
Yes. HL7 Workbench is a free, browser-based HL7 v2 parser, viewer, and validator, launching soon. There is nothing to install and no account to create — you load an HL7 message and it is parsed into a navigable segment tree right in your browser.
All 14 HL7 v2 versions, from v2.1 through the latest v2.9. The built-in specification browser covers every segment, data type, value table, trigger event, and message structure for each version, so you can parse and validate against the exact version your interface uses.
Yes. Parsing, validation, and formatting all run client-side in your browser — your HL7 messages are never uploaded to a server. That makes it safe to inspect production-like messages without sending protected health information anywhere.
Yes. The validator checks messages against the selected HL7 v2 specification in real time, with conformance checking, error reporting, and segment-level diagnostics so you can pinpoint malformed segments, fields, and components.
Parse messages into a tree with segment, field, and component breakdown; decode coded values against HL7 tables; format and clean up raw messages; browse the full v2 specification; and load built-in sample messages for ADT, ORM, ORU, and more.
No — HL7 Workbench runs entirely in the browser, so it works on any operating system without a download. It pairs naturally with Mirth Connect and broader HL7 integration workflows when you take an interface to production.
