What is a Code Formatter?

A code formatter (also called code beautifier or prettifier) is a tool that automatically arranges your source code according to consistent formatting rules. It adds proper indentation, line breaks, and spacing to make your code more readable and maintainable.

Supported Formats

  • JSON - JavaScript Object Notation for data interchange
  • XML - Extensible Markup Language for structured data
  • SQL - Structured Query Language for databases
  • CSS - Cascading Style Sheets for web styling
  • YAML - Human-readable data serialization format

How to Use

  1. Select the format of your code (JSON, XML, SQL, etc.)
  2. Paste your code or upload a file
  3. Click 'Format' to beautify or 'Minify' to compress
  4. Copy the result to your clipboard
