JSON Viewer
Paste or drop a .json file below to explore it as a collapsible, searchable tree — expand only what you need, search across the whole document, and copy the JSONPath to any value.
How to view a JSON file online
- Paste your JSON into the input pane, or drag a
.jsonfile directly onto it. - Browse the collapsible tree on the right — click any branch to expand or collapse it.
- Use the search box to filter to matching keys or values; matches auto-expand their parents.
- Click any key or value to copy its exact JSONPath to your clipboard.
Why use this JSON viewer
Built for large, nested data
Parsing runs in a Web Worker and the tree renders lazily, so deeply nested or multi-megabyte JSON stays navigable instead of freezing the tab.
One-click JSONPath
Stop manually counting array indices and nesting levels — click any value to instantly copy its exact path.
Private by design
Your file never leaves your browser. There's no upload step, which matters if you're viewing an API response or export you shouldn't paste into a random online tool.
No install required
Works entirely in the browser — nothing to download to open and browse a .json file.
Reading JSON as a tree instead of raw text
Raw JSON — especially minified or deeply nested JSON — is genuinely hard to read as plain text: braces and brackets nest many levels deep, and it's easy to lose track of which closing brace matches which opening one. A JSON viewer solves this by rendering the same data as a collapsible tree, where each object or array can be expanded or collapsed independently, so you only look at the branches you actually care about.
This is especially useful for exploring an unfamiliar API response or a large exported .json file: rather than scrolling through thousands of lines, you can collapse everything to the top level, then drill into just the one array or object you need. The search box speeds this up further — type any key name or value fragment and matching nodes stay visible while everything else hides, with their parent branches automatically expanded so you can see exactly where a match sits in the structure.
The one-click JSONPath copy is aimed at a common next step after finding a value: referencing it in code, a query tool, or a bug report. Instead of manually writing out data.users[3].address.city, click the node and the exact path is on your clipboard.
Frequently asked questions
What does a JSON viewer do that a text editor can't?
A JSON viewer renders your data as a collapsible, color-coded tree instead of raw text, so you can expand only the parts you care about, search across the whole document, and copy the exact path to any value.
Can I view a JSON file without uploading it anywhere?
Yes. This viewer parses and renders your file entirely in your browser — the file is never sent to a server, so it's safe for private or sensitive data.
What is a JSONPath, and why would I copy one?
A JSONPath is a compact address for a specific value inside a JSON document, like $.users[2].email. Copying it lets you reference that exact field in code, a query tool, or documentation without retyping the full nested structure.
Does the viewer handle very large or deeply nested JSON?
Parsing runs in a background Web Worker so large files don't freeze the page, and the tree only renders expanded branches, keeping deeply nested documents navigable.
