What is a code beautifier?
A code beautifier (or code formatter) re-indents and re-spaces source code so it follows a consistent, readable style without changing what it does. Our beautifier uses Prettier and dialect-aware formatters under the hood to pretty-print JSON, JavaScript, TypeScript, JSX, CSS, SCSS, LESS, HTML, Vue, XML, Markdown, YAML, GraphQL and SQL. Everything runs locally, so even proprietary code never leaves your machine.
Key features
- 15+ languages with automatic, dialect-aware formatting
- Beautify, minify and validate from one toolbar

Frequently asked questions

Which languages can it format?
JSON, JSON5, JavaScript, JSX, TypeScript, TSX, CSS, SCSS, LESS, HTML, Vue, XML, Markdown, YAML, GraphQL and SQL.
Can it minify as well as beautify?
