How to Use the JavaScript Formatter

Paste minified or compressed JavaScript and get a nicely formatted version with proper indentation, line breaks after semicolons, and structured braces.

Features

  • Auto-Formatting — Adds proper line breaks after braces, semicolons, and commas.
  • String-Aware — Preserves content inside string literals without inserting breaks.
  • Comment Preservation — Keeps single-line comments intact.
  • Indent Options — Choose 2 or 4 space indentation.

    • Common Use Cases

  • Debugging — Make minified production JS readable for debugging.
  • Code Review — Format third-party scripts to understand their logic.
  • Learning — Expand minified examples from tutorials or Stack Overflow.

    • Why Use This Tool

    Minified JavaScript is essential for production but impossible to debug. This tool bridges the gap, letting you quickly format code for reading without setting up a full development environment.
