JSON Viewer Online

Updated 2026-07-09

View and explore JSON online for free in an interactive, collapsible tree. Paste, type, or drop a file and SnapTools renders it as a navigable structure you can expand, collapse, search, and copy from — including one-click copy of any value's JSONPath. Everything runs in your browser, so nothing is uploaded.

A formatter makes JSON readable; a viewer makes it explorable. When you're staring at a huge API response or a deeply nested config, the tree lets you collapse the noise, jump straight to what you need, and grab the exact path to any value — far faster than scrolling through pretty-printed text.

// how to use

1 Paste, type, or drop a JSON file into the input panel.
2 Explore the interactive tree — click any arrow to expand or collapse, or use Expand all / depth.
3 Hover a node to copy its value or its JSONPath; use search to jump to matches.

// examples

// faq

A formatter pretty-prints JSON as text. A viewer renders it as an interactive, collapsible tree so you can explore deeply nested data, collapse the parts you don't care about, search, and copy a specific value or its path without scrolling through thousands of lines.

Hover any node and use the copy-path action to get its exact JSONPath, like data.items[0].name, ready to paste into code or a JSONPath tester.

Yes. The tree renders lazily and large arrays start collapsed, so big documents stay responsive. Everything runs in your browser, so even large files never leave your machine.

The viewer shows a clear error with the position of the problem so you can fix it. You can also switch to the raw view to inspect the text.

No. Parsing and rendering happen entirely in your browser — nothing is sent to a server.
