What is the FHIR Bundle Visualizer?

A FHIR Bundle is a tree-structured document whose entries cross-reference one another by fullUrl or Type/id. Reading it as raw JSON is painful. The Bundle Visualizer parses any FHIR R4 Bundle and lays out every entry side-by-side, resolving references both ways so you can see at a glance how the document is wired.

What it surfaces

Per-entry summary: resource type, id, fullUrl, request/response (transaction bundles).
Outgoing references — click to scroll to the target entry.
Incoming references — see which entries point at this one.
Dangling references — a warning callout for any link that doesn't resolve.

Want to compare or validate?

Send any Bundle straight to the FHIR Validator or the FHIR Diff with the buttons in the toolbar.
