JSON Tree Viewer
Paste JSON to explore it as a collapsible tree. Search, inspect paths, and see structure at a glance.
What is a JSON Tree Viewer?
A JSON Tree Viewer turns raw, minified, or deeply nested JSON into a readable, collapsible tree, so you can see how an object or array is actually structured instead of scanning a wall of brackets and commas. It's built for API responses, config files, exported data, and anything else that's technically valid JSON but hard to read as plain text.
How to use it
- Paste your JSON into the input box, or upload a
.jsonfile. - Click View Tree to parse and render it.
- Click the arrows to expand or collapse objects and arrays, or use Expand All / Collapse All.
- Use the search box to highlight matching keys and values anywhere in the tree.
- Click any line to select it and copy its exact path with the Copy button.
Why use a tree view instead of raw text?
Nesting is the hardest part of reading JSON by eye — it's easy to lose track of which closing brace belongs to which object. A tree view makes that structure visible: keys and values are color-coded by type, arrays and objects show their size at a glance, and you can collapse the parts you don't need so you can focus on the section you're debugging.
Frequently asked questions
Is my JSON uploaded anywhere?
No. Parsing and rendering happen entirely in your browser — nothing you paste or upload is sent to a server, so it's safe to use with private data.
What happens if my JSON is invalid?
The tool shows the parser's error message, including the position of the problem, so you can quickly find and fix the issue in your input.
What does the "path" mean?
The path shows exactly how to reach the selected
value from the root, using dot notation for object
keys and bracket notation for array indexes, e.g.
$.tools[0].name.
Does search look inside collapsed nodes?
Yes. Searching automatically expands any branch that contains a match, and hides branches that don't, so you only see what's relevant to your search term.
