About JSON viewing
Parse once, browse as a tree
The viewer sends the pasted text to a browser worker, parses it with JSON.parse, and renders the result as an expandable tree. Invalid JSON is treated as a parse failure, so this page is for inspecting valid JSON data rather than repairing loose JavaScript objects.
FAQ
Common questions and answers about this topic.
What does this viewer do?
It displays valid JSON in an interactive tree view with expand and collapse controls, JSON Path navigation, and path copy support for nested data structures.
How is this different from the JSON Formatter?
The formatter produces formatted text output, while the viewer provides an interactive tree for exploring nested structures with path navigation and copy features.
Can I jump to a nested value?
Yes, hover a node to capture its JSON Path, copy that path, or type a path into the bar to jump to a nested node in the rendered tree.
Is my data sent to any server?
No, JSON viewing and exploration run entirely in your browser. Your data is parsed locally with JavaScript and never uploaded to any server.
How do I open a .json file?
A .json file is plain text, so any text editor can open it. To read it as a structure instead of raw text, open the file in an editor, copy its contents, and paste them here; the viewer parses the text and shows it as an expandable tree, and you can download the text again as a .json file. Nothing needs to be installed.
How is this different from a JSON viewer browser extension?
An extension formats JSON responses automatically when you open a URL in the browser. This page needs no installation and works with any JSON you can paste, such as a log line, a config snapshot, or a payload copied from a terminal or a request inspector. It adds JSON Path hover, copy, and jump-to-path navigation on top of the tree.
Can I search for text inside the JSON?
No. The viewer navigates by JSON Path, not by full-text search. If you know the key or index, type its path in the path bar to jump straight to that node; if you need to find a value by its contents, use the JSON Formatter to produce formatted text and search it with your editor or browser find. Invalid JSON is reported as a parse failure rather than being repaired.
