HL7 v2 message validator
Paste a message and read it field by field. Syntax and the HL7 standard are checked against the version in MSH-12 or the one you choose; what a specific receiving system additionally requires (mandatory fields, allowed codes, lengths) is not, unless you load its profile. Paste the receiver’s ACK to relate its errors to the message.
