No, the Response Formatter processes data locally in your browser. Paste API response data directly and it will be formatted, syntax-highlighted, and displayed with proper indentation. This makes it safe for formatting responses containing sensitive production data.
The formatter handles JSON, XML, HTML, YAML, and plain text API responses with automatic format detection. JSON responses are pretty-printed with syntax highlighting, XML is properly indented, and headers are separated into a clean table view. Malformed responses are displayed with error indicators.
