Standard structural rules applied when converting minified scripts into clean, readable code.

Language Construct Minified Code Pattern Formatted Code Pattern Formatting Benefit
Function Definitions function add(a,b){return a+b;} function add(a, b) {
  return a + b;
}		 Parameter spacing and body indentation
Conditionals & Loops if(x>0){doX();}else{doY();} if (x > 0) {
  doX();
} else {
  doY();
}		 Distinct branch visibility and block separation
Object Literals {id:1,name:"test",active:!0} {
  id: 1,
  name: "test"
}		 Key-value pair alignment and readable properties
Array Definitions [1,2,"three",{val:4}] [
  1,
  2,
  "three"
]		 Element itemization and bracket balancing

Frequently Asked Questions

What does a JavaScript beautifier do?

A JavaScript beautifier unpacks minified, compressed, or single-line JavaScript and TypeScript scripts into readable code with normalized line breaks, indented lexical scopes, spaced operators, and standardized curly bracket formatting.

Can a beautifier de-obfuscate mangled variable names?

A beautifier restores code structure and indentation, but it cannot recover original variable names if they were shortened or mangled (e.g., from 'userData' to 'a') during production minification or obfuscation unless a source map is supplied.

Will beautifying break string literals or regexes?

No. The formatting parser protects string literals (single, double, and backtick template literals) and regular expression literals from unexpected indentation or newline insertion.

Is my JavaScript code uploaded to any external server?

No. All formatting logic runs 100% client-side inside your browser engine. Your confidential scripts, functions, and API logic never leave your device.
