Drop one or more .hl7 files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
HL7 to CSV
Converting a .hl7 font to .csv repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .hl7 font to .csv repackages the same glyphs and metrics for a different delivery target. An .hl7 file holds one or more HL7 version 2 messages: pipe-delimited healthcare interchange records made of segments — MSH for the header, PID for the patient, PV1 for the visit — each split into fields, components and subcomponents by a delimiter hierarchy declared in the message itself.
A .csv file is a comma-separated values table: plain-text rows with commas between fields, optionally quoted. It is probably the most widely produced data format in existence, emitted by everything from banking portals to lab instruments. For this route the practical draw is supported by effectively every data tool ever written and human-readable and hand-editable in a pinch — balanced against no type information — Excel famously strips leading zeros and mangles dates on open, which is worth knowing before you commit a large batch.
Why convert HL7 to CSV?
The practical trigger for this conversion is usually a mismatch: with .hl7, extremely terse; a message is unreadable without a segment reference to hand. Switching to .csv buys you supported by effectively every data tool ever written, which is why it is the better fit for exports from databases, CRMs, and banking systems. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
HL7 vs CSV at a glance
| Aspect | HL7 version 2 message (.hl7) | CSV table (.csv) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | segments are separated by CARRIAGE RETURNS, not newlines. This is the standard, not a Windows artefact, and readers that split on \n mis-parse real messages | fields containing commas, quotes, or newlines are wrapped in double quotes with embedded quotes doubled — the rule that breaks every naive split-on-comma parser |
| Strongest at | inspecting hospital interface traffic during integration work | exports from databases, CRMs, and banking systems |
| Weak spot | extremely terse; a message is unreadable without a segment reference to hand | no type information — Excel famously strips leading zeros and mangles dates on open |
Pick CSV as the output
Select .csv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if CSV is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid CSV file. Outputs keep the original filename with the .csv extension.
HL7 to CSV questions, answered
Will converting HL7 to CSV lose quality?
There is no visual quality to lose — hl7 is text-oriented and csv is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert HL7 files here?
Yes — the .hl7 file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the CSV file work?
Every spreadsheet, database, and programming language handles CSV, and browsers or text editors open it as plain text. The catch is dialect drift: delimiter, encoding, and quoting choices differ enough that robust importers always offer manual overrides.
Will the CSV file be bigger or smaller than my HL7?
It depends on the content: fields containing commas, quotes, or newlines are wrapped in double quotes with embedded quotes doubled — the rule that breaks every naive split-on-comma parser. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my HL7 file?
In .hl7, the MSH header — sending and receiving applications, timestamp, message type, control ID — is preserved in the JSON output. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
