JSON Tree Viewer

This tool parses any JSON you paste or upload and renders it as an interactive, collapsible tree instead of a flat block of text. Each object and array becomes a branch you can expand or collapse, while individual keys show their value type — string, number, boolean, or null — in a distinct color so you can scan a large response without reading every character.

Typing in the search box filters the tree down to matching keys and values, automatically opening only the branches needed to reach each result and closing the rest. Clicking the copy icon next to any node copies that value on its own, while the path icon copies the exact dot-and-bracket path (for example, data.users[2].email) so you can paste it straight into code, a test assertion, or a bug report. A stats line at the bottom of the tree tracks how many keys and how many levels deep the current JSON goes.

If the input isn't valid JSON, the tool flags the parsing error immediately instead of showing a blank tree. All parsing and rendering happens locally in your browser, so pasting API responses, configuration files, or JSON containing tokens and credentials never sends that data to a server.
