Edit, sort keys, re-indent and refine your JSON with live preview.
JSON Editor Online lets you edit, sort, and validate JSON files in a clean workspace that shows your data the way it’s meant to be read. If you’ve ever wrestled with a messy API response or a config file that’s impossible to scan, this tool gives you a tree view, syntax validation, and one-click formatting. Paste raw data, use the Beautify button to tidy it up, and toggle key sorting or string escaping to fit your needs. Whether you’re a developer debugging an endpoint or an analyst checking a data structure, you get a live preview that reflects your changes.
