Click a node to expand/collapse. Hover any value and click the copy icon to copy it. Everything runs in your browser — your data is never uploaded.
Explore JSON as an interactive collapsible tree, free. A JSON viewer renders raw JSON (RFC 8259) as an interactive, collapsible tree so you can read deeply nested objects and arrays without counting brackets. This tool parses your JSON in the browser and lets you expand or collapse any node, search by key or value, and copy any value or subtree on hover — entirely on your device, with no upload.
It turns minified or deeply nested JSON into a navigable tree with search and copy-on-hover, so you can find and grab the value you need in seconds. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Every object and array becomes an expandable node, so you can drill into nested structures and collapse what you don't need.
Filter the tree by key or value to jump straight to the data you're looking for in large documents.
Hover any node to copy its value or entire subtree to the clipboard — no manual selecting.
Your JSON is parsed locally in the browser; nothing is uploaded, logged, or stored.
It parses raw JSON and displays it as an interactive tree of expandable nodes, instead of a flat block of text. That makes deeply nested objects and arrays far easier to read, search, and copy from than scrolling through minified JSON.
Yes. Because parsing runs locally, there's no upload limit beyond your device's memory, and collapse/expand plus search let you navigate large, deeply nested documents without losing your place.
It's a read-and-explore viewer focused on navigating, searching, and copying. For reformatting use the JSON Formatter; for validation use the JSON validator.
No. The JSON is parsed entirely in your browser — nothing is sent to a server, so it's safe for sensitive payloads.
The viewer needs valid JSON. Common issues are trailing commas, single quotes instead of double quotes, or unquoted keys — format or validate the JSON first, then view it.
