FHIR Resource Visualizer

Visualize FHIR resources as an interactive tree. Inspect nested elements, references, and extensions privately in your browser.

• Explore any FHIR resource or Bundle as a collapsible tree.
• Inspect nested elements, extensions, and references without scrolling raw JSON.

FHIR Toolbox is a free, privacy-first collection of HL7 FHIR utilities by Omindra Labs. Every tool performs zero-server processing — your health data never leaves your device.
