Code Formatter

A powerful, browser-based code beautifier and formatter that supports multiple programming languages and data formats. Powered by Prettier, it ensures consistent code style and readability with extensive customization options.

🚀 Why Use Code Formatter?

Maintaining clean and consistent code is essential for readability and collaboration. Code Formatter provides a fast, secure, and highly configurable way to beautify your code without ever leaving your browser.

Developer-Centric Features

  • Multi-Language Support: Format everything from JavaScript and TypeScript to YAML and Markdown.
  • Deep Customization: Fine-tune indentation, line width, quotes, and more to match your project's style guide.
  • Specialized JSON Tools: Beyond formatting, you can sort keys alphabetically, minify data, or simply validate structure.
  • Privacy First: All processing happens locally in your browser. Your code is never sent to a server.
  • Persistent History: Keep track of your last 10 formatting sessions with local history storage.
