Why FHIR Data Remains Hard to Understand

Even with widespread adoption of FHIR APIs, teams still struggle to work with raw JSON payloads. Reviewing FHIR data in Postman or plain text editors is inefficient and difficult to share across clinical, QA, and product teams. 

FHIR Viewer solves this by turning raw JSON into a side-by-side, human-readable view that is easy to interpret, share, and act on. Whether you are debugging a single bundle or reviewing data from a live server, our FHIR Viewer simplifies the entire process.
