What JSON features are supported?

The viewer supports the full JSON specification: nested objects, arrays of any depth, strings, numbers (integer and float), booleans (true/false), and null values. Unicode strings are displayed correctly.

Can I view very large JSON files?

Yes, but very large files (thousands of nodes) may take a moment to render. For performance, deeply nested arrays or objects are collapsed by default. Use Expand All with caution on files with tens of thousands of nodes.

What does the path breadcrumb show?

When you hover a node, the breadcrumb shows the JavaScript-style path to reach that value from the root, such as data.users[2].email. This is useful for writing code that accesses specific nested values.

Is my JSON data private?

Yes. Everything runs in your browser. Your JSON is never sent to a server and is not stored anywhere.

이 도구에 대해

Paste any JSON into the input and see it rendered as a fully interactive collapsible tree. Each node can be expanded or collapsed with a click. Values are color-coded by data type: strings in green, numbers in blue, booleans in orange, null in gray, arrays in purple, and objects in the default text color. Hover over any node to see its full dot-notation path in a breadcrumb below the tree. Click any primitive value to copy it to your clipboard. Arrays and objects show their element count. All processing happens in the browser — no JSON is sent to any server.
