View JSON as an interactive collapsible tree
Explore large JSON documents as a navigable tree: expand and collapse nodes, see value types at a glance, and drill into deeply nested structures without losing your place. Everything renders locally in your browser.
Frequently Asked Questions
- Why use a tree view instead of formatted text?
- For deeply nested or very large JSON, a tree lets you collapse the parts you do not care about and navigate structure visually — much faster than scrolling formatted text.
- How large a JSON file can the viewer handle?
- Documents of several megabytes render fine in modern browsers. Collapsed-by-default nodes keep the initial render fast even for large payloads.
- Is my JSON sent to a server?
- No — parsing and rendering are done entirely in your browser, so production API responses are safe to inspect.
- How do I extract a specific value from deep JSON?
- Navigate the tree to locate it, or use our JSONPath Tester to query values programmatically with expressions like $.store.book[0].title.
