Format data without leaving the browser.
Use local formatters for JSON, XML, SQL, Base64, URLs, and regular expressions.
Browser-based formatters are useful when you need fast feedback without opening a full IDE. Paste messy JSON, XML, or SQL, clean it instantly, and continue debugging. For sensitive payloads, local-first tools are especially helpful because you can avoid sending raw data to random online services.
All processing is performed directly in your browser's client-side sandbox. Your files and data remain secure, and no uploads or external transmissions occur.
