Free JSON Viewer — Interactive Tree Explorer
Paste any JSON and explore it as a collapsible, syntax-colored tree instead of a flat wall of text. Expand and collapse nested objects and arrays to focus on the part of the payload you actually care about — ideal for digging through large API responses or config files.
How to Use It
Paste your JSON into the left panel. It's parsed instantly and rendered as an interactive tree on the right — click the arrow next to any object or array to expand or collapse it. Switch to "Raw Formatted" to see the same data as plain indented JSON, and use Copy to grab it.
Example
Pasting a nested object like {"user": {"name": "Alice", "roles": ["admin","editor"]}} renders "user" as a collapsible node — collapse it to hide the details, or expand "roles" on its own to check just that array.
Common Use Cases
- Exploring a large, deeply nested API response without scrolling through every field.
- Reviewing a configuration file's structure before editing it.
- Collapsing irrelevant branches to focus on one part of a payload during debugging.
- Getting a quick visual sense of a JSON document's shape and depth.
FAQs
How is this different from the JSON Formatter?
The JSON Formatter focuses on pretty-printing and minifying JSON as text. This viewer is built for exploration — it renders the same data as an interactive, collapsible tree so you can expand only the parts you need, though a raw formatted view is also available here.
Does it work with large JSON documents?
Yes — everything runs in your browser, and collapsing large branches you don't need makes it easy to navigate even sizeable payloads without the page becoming sluggish.
Is my JSON data uploaded anywhere?
No — parsing and rendering happen entirely client-side in your browser. Your data is never sent to a server.
