Code Formatter & Converter Tools

Code formatting and conversion tools organize common source code and structured data. They can turn compressed or poorly indented code into a clearer hierarchical structure for easier reading, debugging, and maintenance.

Common code formatting

  • JavaScript formatting
  • HTML formatting
  • CSS formatting
  • XML data formatting
  • JSON and other structured data formatting

Why format code?

Production JavaScript, CSS, and HTML are often minified to reduce resource size. Minified code usually has fewer line breaks and less indentation, making manual analysis difficult. A formatter can restore structure and improve readability.

Use cases

Code formatting is useful for frontend development, API debugging, source-code analysis, code review, configuration inspection, and development testing.
