About JSON Viewer Pro

JSON Viewer Pro turns structured data into interactive diagrams. You paste or load JSON, YAML, XML, CSV, TOML, TOON or Mermaid and see it as a graph, table or chart that you can explore. It is built for developers, analysts and data practitioners who find raw nested text hard to read.

Features include a graphical comparison that shows differences between two JSON files side by side, custom diagrams, editing JSON directly from the diagram, AI-assisted diagram generation, JSON repair and generation, REST API testing with diagrams, graph download, a structured editor and a Mermaid diagram editor. Cloud storage is offered for saved work, and a Chrome extension is available.

The homepage lists a free plan at $0 per month for viewing and exploring JSON, and mentions upgrading when you are ready. The site also has pages for docs, use cases such as API design and JSON Schema, a changelog and a blog.
