Format config files and inspect parsed structure
Use this YAML, TOML, and XML formatter to beautify structured config files, validate syntax, and preview parsed data as JSON where possible. It helps with infrastructure configs, app settings, manifests, and documentation examples.
The parser feedback is useful when indentation, quoting, arrays, or nested tags make a configuration file hard to scan.
