About the Free JSON Tree Viewer

The JSON Tree Viewer turns any JSON document into an interactive, collapsible tree. Expand and collapse branches, search and highlight matching keys and values, jump between matches, and copy any node's path — all without sending your data anywhere.

Key Features

Interactive Tree: Fold and unfold objects and arrays with a single click, with type-colored values and key counts.
Live Search: Find keys or values instantly — matching nodes are highlighted and searched branches auto-expand.
Match Navigation: Press the arrow to jump straight from one match to the next.
Copy Paths: Grab a JSONPath-style path to any node (e.g. seo.keywords or tools[2]).
Source Mode: Flip to a formatted source view of the same document.
File or Paste Input: Paste JSON or upload a .json file.

When Is a Tree Viewer Useful?

Tree viewers shine when JSON gets big. Browsing a deeply nested API response with search is far faster than reading raw text, and copying exact paths is invaluable when you are writing selectors, JMESPath expressions, or Ethereum RPC filters.
