When working with Python APIs and scripts, you often deal with JSON responses from libraries like requests or json.dumps() output that lacks readable formatting. This tool lets you paste raw Python JSON output and instantly convert it into a well-indented, syntax-highlighted format. Whether you are debugging Flask endpoints or inspecting Django REST Framework responses, proper JSON formatting saves you from squinting at single-line blobs of data.
Format, minify, and validate JSON — instantly, in your browser.
