About

A powerful JSON formatting tool that opens in a full browser tab for maximum viewing space.

Features:

Full-page split view — editable JSON on the left, formatted output on the right, updated in real time
Collapsible tree view with syntax highlighting (strings, numbers, booleans, null, keys all color-coded)
Smart search — type a keyword to instantly highlight all matching keys and values, auto-expand matched nodes, and show match count
Draggable split panel — resize the editor and viewer freely by dragging the divider
Hide/show editor — collapse the left panel to view formatted JSON in full screen
Copy formatted or minified JSON with one click
Beautify or minify the input JSON directly in the editor
Extract JSON from any webpage — click "From Page" to detect and format JSON on the current tab
Paste from clipboard with one click
Works entirely offline — no data is sent anywhere, everything runs locally in your browser
Perfect for developers, API testers, and anyone who works with JSON data regularly.
