Online JSON viewer with structure, stats and tables
Paste JSON to inspect it as a collapsible tree, a spreadsheet-like grid, or a structure graph — with type badges, depths and path copying built in.
More than a tree
The viewer detects arrays of objects and offers a grid, profiles field cardinality and null frequency, and can draw the document structure as a node-link graph. Every node exposes its JSONPath, JSON Pointer and JavaScript property path.
Safe with untrusted data
JSON is data, never executed. There is no eval, no script injection from document strings, and the page keeps a strict content security policy. Rendering is virtualized so a large array does not create a DOM node per record.
Questions
Can I view JSON from an API response?
Paste the response body directly, or import a HAR file in the API workbench to keep status codes and headers alongside the body.
Does viewing require an account?
No. There is no account, no server-side storage and no analytics that read document content.
Go further in the studio
This page is intentionally a single-purpose tool. The full studio adds synchronized views, profiling, data-quality rules, schema comparison, three-way merge, transformation pipelines, timelines and local persistence. Open it with the same document and continue where this page stops.
