About this JSON viewer

Deeply nested JSON is tiring to read as text. This free online JSON viewer shows it as an interactive, collapsible tree: expand and collapse objects and arrays, search keys and values, and click any node to copy its path.

It works in your browser and nothing is uploaded. For indented text use the JSON formatter. To run queries against the same data use the JSONPath tester, or reshape it with JSON to CSV.

Frequently Asked Questions

Everything you might want to know about the online JSON Viewer.

A JSON viewer shows a JSON document as an interactive, collapsible tree instead of plain text. Objects and arrays become nodes you can expand or collapse, so large payloads are easy to explore and understand at a glance.
The JSON Formatter neatly indents JSON as text. The viewer turns it into a tree you can navigate: collapse objects and arrays, see how many items each contains, and click any key to copy its path. To compare two JSON documents instead, see JSON Compare.
No. Everything happens locally in your browser. Your JSON is parsed and displayed on your own machine and is never uploaded, stored, or logged.
Yes. Type in the Search tree box and the viewer highlights matching keys and values, automatically expanding the branches that contain them and hiding the rest.
Click any key in the tree. Its location is copied to your clipboard as a path such as library.book[2].title, ready to paste into your code.
You can paste text or upload a file up to 10 MB. Very large documents (tens of thousands of nodes) are best viewed with the JSON Formatter, and the viewer will suggest this when a document is too big to draw as a tree.
