About
Simple synthetic test data for healthcare integration work.
HL7/FHIR Test Data Generator is a browser-based utility for creating fictional HL7 v2 and FHIR examples for interface testing, demos, QA scripts, and documentation.
Purpose
Built for integration testing, not patient care
The tool creates random, fictional examples that look like common healthcare integration payloads. It is intended for people who need quick sample data while building routes, testing parsers, preparing demonstrations, or writing mapping documentation.
Synthetic-only
Generated names, identifiers, addresses, and clinical-looking values are fictional and should not be treated as real records.
Low-maintenance design
The site is static so it can be hosted publicly with minimal infrastructure and no custom customer implementation.
Current scope
Supported random scenarios
- HL7 ADT^A01 inpatient admission
- HL7 ADT^A03 discharge
- HL7 ADT^A04 outpatient registration
- HL7 ADT^A08 patient/update
- HL7 ORU^R01 pathology result

- FHIR Patient
- FHIR Encounter
- FHIR Observation
- FHIR DiagnosticReport
- FHIR Bundle
Important limitation
Not a validator or standards authority
The generated output is sample-oriented. It may be useful for demonstrations and early testing, but it does not guarantee conformance with a local interface specification, national implementation guide, FHIR profile, terminology binding, or production receiving system.
