What JSON Tree Viewer does

Explore JSON as a collapsible tree with paths, types, counts, search, and source-preserving local parsing.

Also searched as viewer, tree, tree view, browse, explore, navigate, expand, collapse.

Retain one parsed document

Render nodes lazily

Copy paths or values without reparsing

Moving from tree to table, query, schema, or analysis reuses the same document handle in the worker.

QUESTIONS, ANSWERED

Does jsontools.me upload my JSON?

No. The document is parsed and processed by json-buf inside a dedicated WebAssembly worker on your device.

Does it work offline?

Yes. After the application shell and engine have loaded once, the installable PWA keeps the tools available without a network connection.
