HL7 Message Inspector
Paste an HL7 v2 message to see its segments, fields and components laid out clearly, with a copyable path for every value.
Read this first.
This tool shows structure: where each segment, field, repetition, component and subcomponent sits and what it contains.
It is not a conformance validator, and it does not interpret field meanings, because those depend on the HL7 version and your local profile.
When you choose Inspect Message, the text is sent to this site's server, parsed in memory and returned.
It is not stored, logged or sent to any third party. Use synthetic or de-identified messages only.

One segment per line. CR, LF and CRLF line endings are all accepted. Limit: 20 KB. Samples contain fictional data only.
Results
Choose Inspect Message to parse the text above.
Parsing errors
The message could not be parsed, so there is no parsed output.
Structural warnings
The message was parsed, but these things look unusual. A warning is not a validation result.

Field details
Select a field to see its position, raw value, repetitions, components and subcomponents.
Original message
Shown one segment per line. Select a line to open that segment. Values are displayed exactly as received.
Path notation: PID-5.1 field 5, component 1 · PID-5[2].1 second repetition ·
OBX[2]-3.2 second OBX segment · OBX-3.2.1 subcomponent. Plain paths such as
OBX-3 refer to the first occurrence of a repeated segment.
