Js To Json
Convert JavaScript object literals to valid JSON. Fix unquoted keys, trailing commas, single quotes. Browser-based, instant conversion.
JavaScript Beautification
Minified JavaScript removes whitespace and shortens variable names for size reduction. While essential for production, minified code is nearly impossible to read or debug. Our formatter restores structure and readability.
Modern JavaScript Support
- ES6+ syntax: Arrow functions, template literals, destructuring
- JSX: React component syntax properly formatted
- TypeScript: Type annotations and generics handled correctly
- Modules: Import/export statements formatted consistently
Style Options
Brace style: Choose between collapse (same line), expand (new line), or end-expand formats to match your project's conventions.
Indentation: Configure tabs or spaces with customizable size.
Spacing: Control space around operators, after keywords, and inside parentheses.
Debugging Minified Code
When analyzing third-party libraries or debugging production issues, formatted code reveals program logic, control flow, and data structures that are hidden in minified output.
