What is JavaScript Beautification?

JavaScript beautification reformats compressed or minified JS code into a readable, properly indented format. This tool handles ES6+ syntax including arrow functions, template literals, destructuring, and async/await. It properly indents nested blocks, adds line breaks after statements, and formats object literals for maximum readability.

When to Use a JS Beautifier

Use this tool when debugging minified production code, reviewing obfuscated scripts, cleaning up auto-generated code, or reformatting code that lost its indentation. The beautifier preserves the logic while making the structure visible.
