How To Use
Choose the parser that matches your source, paste source code or markup into the input editor, and adjust formatting options like indentation, print width, quotes, and trailing commas.
Use Preview Output to inspect the result first, or Format Code to write the formatted version back into the source editor.
Formatting runs locally with the selected parser, so this works well as a code formatter tool or code prettifier for TypeScript, JSON, HTML, CSS, Markdown, and YAML without sending code to a server.
