Paste your JSON to format it with a collapsible tree view, validate it, or minify it — all in your browser.
A JSON Beautifier formats minified or unformatted JSON and displays it as an interactive collapsible tree. Click the ▶ / ▼ icon next to any object or array to collapse or expand that node. This makes it easy to navigate large JSON structures without scrolling.
Press Ctrl + Enter inside the input box to instantly beautify.
