JSON Viewer & Tree Explorer
Browse JSON as an interactive, collapsible tree. Search keys and values, copy any node or path, and inspect data types, counts and size stats.
A better way to read JSON
The JSON viewer renders any document as an interactive, collapsible tree so you can navigate deeply nested structures without getting lost. Search across keys and values, copy any node or its JSONPath, and inspect data types and item counts at a glance.
Unlike reading raw JSON in a text editor, the tree view lets you collapse large sub-trees you are not interested in and focus on exactly the data you need. This is especially useful when exploring API responses, configuration files or database exports that span hundreds of nested keys.
Frequently asked questions
How do I explore large JSON files?+
Paste or load your JSON and use the collapsible tree view. You can search keys and values, expand only the branches you need, and copy any node or its path.
Can I see the data type of each value?+
Yes. Hovering a node shows its type, and containers display item counts so you can understand structure at a glance.
What is a JSON tree viewer?+
A JSON tree viewer renders a JSON document as an interactive, hierarchical tree. You can expand or collapse any object or array branch, which makes it much easier to navigate deeply nested data than reading raw text.
Can I collapse and expand nodes?+
Yes. Click any object or array node to toggle it. You can also expand or collapse the entire document at once using the toolbar buttons.
Does it work with large files?+
The viewer handles most real-world JSON files well. For very large documents the initial render may take a moment, but once loaded you can navigate freely without lag because only visible nodes are rendered.
