About Health Data Tools

Health Data Tools is a collection of lightweight browser-based utilities for healthcare integration developers, interface analysts, QA testers, and technical teams.

Available tools

The HL7/FHIR Test Data Generator creates fictional HL7 v2 and FHIR examples for demos, QA, documentation, and interface testing.

The FHIR JSON Formatter & Resource Viewer formats and explores FHIR resources and Bundles with resource summaries, path search, entry browsing, and internal reference checks.

The FHIR Resource Diff & Comparison Tool compares two FHIR JSON resources or Bundles and identifies structured property, resource, repeating-element, and reference changes.

The CDA & Clinical XML Viewer formats and explores CDA or clinical XML with a namespace-aware tree, common CDA header summaries, section navigation, narrative text extraction, and practical structural checks.

The CDA & Clinical XML Diff Tool compares two CDA or clinical XML documents and identifies structured header, section, entry, narrative, attribute, value, and internal reference changes with CDA-aware matching.

The X.509 & PEM Certificate Decoder & Inspector decodes and inspects certificate validity, subject and issuer names, public-key details, SANs, key usage, extensions, fingerprints, and basic relationships between certificates pasted in the same bundle.

The HL7 Message Formatter & Viewer turns pipe-delimited HL7 v2 messages into a readable segment and field view, with common labels and component breakdowns.

The HL7 Message Diff & Comparison Tool compares two HL7 v2 messages and identifies added, removed, and changed segments, fields, repetitions, components, and subcomponents.

Privacy-first design

The tools are designed to run in the browser without requiring a login or server-side message storage. Users should still never paste real patient data, credentials, secrets, private keys, or confidential production values.

Technical-use scope

These tools are for development and testing workflows only. They are not clinical systems, patient record systems, medical devices, or certified standards validators.
