What is JavaScript Formatter?
The JavaScript Formatter is a free online tool that beautifies, formats, and minifies JavaScript code instantly. It's ideal for making minified or obfuscated scripts readable, enforcing consistent indentation and brace style, and preparing code for review or debugging. The formatter handles modern JavaScript including ES6+ syntax, arrow functions, destructuring, template literals, and async/await patterns without breaking your code.
How to Use the JavaScript Formatter
- Paste your JavaScript code into the input editor.
- Click Format to apply consistent indentation and formatting rules.
- Review the output to confirm the structure and logic are intact.
- Use the Minify option to compress the script for production deployment.
- Copy the formatted or minified code to your clipboard.
Frequently Asked Questions
Can the formatter handle modern ES6+ JavaScript?
Yes, the formatter fully supports ES6+ syntax including arrow functions, classes, template literals, destructuring, spread operators, and async/await.
Will formatting change what my JavaScript does?
No, formatting only affects whitespace and indentation. The logic, variables, and functionality of your code remain completely unchanged.
Can I use this to make minified JavaScript readable?
Yes, this is one of the most common use cases. Paste any minified or bundled JavaScript and the formatter will restore readable indentation and line breaks.
Is this tool the same as a JavaScript linter?
No, a formatter enforces code style while a linter checks for bugs and code quality issues. This tool focuses on formatting only and does not report logical errors.
