About PawFormatter

PawFormatter is a free, privacy-first toolkit for beautifying and converting structured data. It supports JSON, YAML, TOML, XML, and TOON, and it runs entirely in your browser.

Privacy first

Your data is processed locally using open-source JavaScript libraries. Nothing is uploaded to a server, and nothing is stored. You can even use the tool offline once the page has loaded.

What it does

• Beautify (pretty-print) JSON, YAML, TOML, XML, and TOON.
• Convert data between any of those formats.
• Copy the result or download it as a file.

Open-source libraries

PawFormatter is built with permissively licensed open-source libraries, including js-yaml, smol-toml, fast-xml-parser, and the TOON reference library.
