JSON Viewer — Explore Nested JSON as a Tree
Visualize JSON as an interactive, collapsible tree — click any node to copy its path.
What is a JSON viewer?
A JSON viewer (also called a JSON tree viewer) transforms dense, nested JSON into an interactive tree you can expand, collapse, and search — the fastest way to understand deeply layered API responses, configs, or document structures. Load your JSON and every object and array becomes a collapsible node; click to drill down, click again to fold it away. Like every tool on jsons.site, the tree is built entirely in your browser — your data never leaves your device.
Why use a tree viewer instead of a formatter?
Search works across collapsed branches, so you can find a key buried ten levels deep without opening anything manually. Hover any node to copy its full JSON path (for example $.users[3].address.city) straight to the clipboard for use in JSONPath queries or code. Expand All / Collapse All give instant overviews, and large documents stay responsive because nothing is uploaded and no server round-trip occurs.
How to use the tree viewer.
- Paste your JSON in the left editor
- Click "Build Tree" to generate the visual tree
- Expand/collapse nodes by clicking the arrow icons
- Search keys using the search box to filter the tree
- Copy paths by hovering over any node and clicking the copy button

FAQ.
What is a JSON viewer?
A tool that displays JSON as an interactive, collapsible tree of objects and arrays (also called a tree viewer), making nested structures readable at a glance instead of scrolling through flat text.
Can I search inside collapsed JSON nodes?
Yes. The search matches keys across the entire document, including branches that are currently collapsed, and highlights matching nodes with their ancestors.
How do I copy a path to a JSON value?
Hover over any node to reveal the copy button on the right. Click it to copy the full JSON path (e.g., $.store.books[0].title) to your clipboard, ready for JSONPath tools or code.
What do the type badges mean?
Each node shows its data type: string (blue), number (purple), boolean (red), null (gray), object (with child count), and array (with item count).
Is my JSON uploaded to view it?
No. The tree is rendered locally by JavaScript in your browser. Nothing is transmitted, stored, or logged — your data never leaves your device.
