JSON Formatter, Validator & Viewer

About the JSON formatter

This tool parses JSON with the browser's native JSON.parse, so validation errors match exactly what your own code would throw. Formatting, minifying, and sorting all happen in memory in this tab — nothing is uploaded, logged, or cached on a server, which matters if you're pasting real API responses or config that contains customer data.

Use the tree view to collapse and explore deeply nested objects and arrays — hover any node to see its full path in the breadcrumb bar, click the breadcrumb to copy that path, or use search to jump straight to a key or value. Switch to raw view to copy a plain formatted string.
