JSON visualizer

← All tools

Paste JSON to browse it as a collapsible tree. Click a node for its path and value, search keys and values, expand or collapse branches, and see structure stats — all rendered as plain text (no HTML injection).

Your JSON never leaves the browser — no upload, no server.

About this tool
Large JSON payloads are hard to scan as raw text. A tree view shows structure at a glance: object keys, array lengths, and primitive values with JSONPath-style paths like $.store.book[0].title.
Unlike tools that inject HTML into the DOM, this visualizer renders every label and value with plain text nodes — safer when you paste untrusted API responses. Documents over 512 KB are rejected to keep the tab responsive.
