JSON Tree Viewer

Browse pasted JSON as an interactive, expandable tree instead of a flat text block.

FreeBrowser-basedInstant
Tree
Paste or type JSON on the left to explore it as a tree here.

Your files are processed locally in your browser and are not uploaded to our servers. The tree is built and rendered entirely in your browser using your browser's own JSON parser and plain DOM elements — your JSON is never sent to a server.

How to use JSON Tree Viewer

Paste any JSON and this tool turns it into a genuine treeview json structure you can click through: every object and array becomes an expandable node with a live "N keys" or "N items" count when collapsed, and every key or value can be clicked to copy its exact JSON path (like `data.items[2].name`) straight to your clipboard. It's built for exploring an unfamiliar or deeply nested payload — an API response, a config file, a webhook body — to see how it's shaped, rather than for reformatting the text itself.

Key features

  • Expandable/collapsible tree view for objects and arrays
  • Live "N keys" / "N items" counts shown on collapsed nodes
  • One-click "Expand all" / "Collapse all" for the whole document
  • Click any key or value to copy its exact JSON path to the clipboard
  • Syntax-highlighted primitives (strings, numbers, booleans, null)
  • Clear line-and-column error messages for invalid JSON
  • Runs fully client-side — no upload, no size limit from a server

Practical use cases

  • Exploring an unfamiliar API response to find where a field lives
  • Browsing a deeply nested config or webhook payload without scrolling text
  • Copying the exact path to a field for use in code or a JSONPath query
  • Getting a quick sense of a document's shape before writing a parser

Supported formats

Accepted: json-tree

Limitations

  • This is a viewer for exploring structure, not a formatter or validator — it doesn't pinpoint syntax mistakes the way JSON Formatter's detailed error output does
  • Extremely large documents (beyond 5MB) are blocked with a message rather than rendered, to avoid freezing the browser
  • Does not support JSON5 or JSONC comment syntax

Frequently asked questions

Does this tool upload my JSON anywhere?
No. Parsing and rendering happen locally in your browser. Nothing you paste is ever transmitted, logged, or stored.
How is this different from the JSON Formatter tool?
JSON Formatter reformats your JSON as text — pretty-printed or minified — with a line-and-column error message if the syntax is broken. This tool skips the text output entirely and instead turns the same JSON into an interactive tree you click through to explore its shape, expanding and collapsing objects and arrays as you go. If you need to clean up, minify, or pinpoint a syntax mistake, use JSON Formatter; if you want to browse a large or unfamiliar structure and copy the path to a specific field, use this tool.
Can I expand or collapse the whole tree at once?
Yes. The "Expand all" and "Collapse all" buttons above the tree toggle every node at once. By default, nodes deeper than two levels start collapsed so large documents render in a usable state.
What happens if I paste invalid JSON?
The tree is replaced with a status message telling you the syntax error and, when available, the exact line and column. For detailed help fixing malformed JSON, the JSON Formatter tool gives the same position information alongside a full text view of your input.
Is there a size limit?
Documents up to 5MB render as a tree. Beyond that, the tool shows a clear "file too large to render as a tree" message instead of attempting to render it and risking a frozen browser tab.
Does clicking a node copy anything?
Clicking a key or a primitive value copies that node's JSON path (for example `data.items[2].name`) to your clipboard, so you can paste it straight into code that needs to reference that field.
