What you can do

Validate — check a bundle against the official HL7 FHIR specification with the Tenasol Validator, with line and column error locations and severity. Choose the FHIR version to validate against, or supply a custom Implementation Guide.
Browse — every resource as a readable, structured table, grouped by resource type and searchable across the whole bundle.
Graph — an interactive force-directed graph of the references between resources, for seeing how a bundle fits together.
Render — a human-readable view of the clinical record, with observations, conditions and medications grouped under the encounter they belong to.
Code — the raw FHIR JSON, with search.
Samples — example FHIR bundles, so you can explore the tool without your own data.
Privacy — bundles are read and rendered entirely in your browser. Only validation contacts the server, and that runs in memory and is never stored.

FHIR Bundle Relationship Graph

See how every resource in a FHIR bundle connects. The graph view lays out each Patient, Encounter, Observation, and other resource as a node, with an edge for every reference between them — click a node to inspect the resource behind it.

Force-directed layout of every resource-to-resource reference in the bundle
Click a node to jump straight to that resource's details
Runs entirely in your browser — nothing is uploaded just to see the graph
