JavaScript Beautifier – Format & Beautify JS Code Instantly

Use our JavaScript Beautifier to format and clean up your JS code for better readability and easier debugging. Whether you're working with minified code or messy scripts, this tool helps make your JavaScript more structured and professional.

Why Use a JavaScript Beautifier?

Minified or poorly formatted JavaScript is hard to read and debug. A beautifier restores structure by:

• Adding proper indentation and line breaks

How It Works

1. Paste your JavaScript code into the input field
2. Click the "Beautify" button
3. Copy the formatted code and use it in your project

Example

Before:

function test(){var x=1;if(x){console.log("Hello");}}

After:

function test() {
  var x = 1;
  if (x) {
    console.log("Hello");
  }
}
