Instructions
How to use JSON Tree Viewer
Paste or choose valid JSON and build the tree. Use expand, collapse, search and per-node copy controls to inspect paths and values.
Real input and output example
{"user":{"name":"Ada"},"roles":["admin"]} becomes nested object and array nodes with $.user.name and /user/name paths.
Diagnostics and limitations
What this tool reports clearly
Rendering is bounded to 200 children per container and 5,000 nodes to protect browser responsiveness.
Privacy
Files are read with browser APIs and processing runs in a dedicated local Worker. Your JSON is never placed in a network request.
FAQ
Common question
Can values execute as HTML?
No. Keys and values are inserted as text nodes and never interpreted as executable markup.
