What Is a JavaScript Formatter?
A JavaScript formatter, also called a JavaScript beautifier, reorganizes JavaScript source code into a cleaner and more readable structure. It adds consistent indentation and spacing so developers can review, edit, and maintain code more easily.
ToolSwift JavaScript Formatter works directly in your browser. Paste formatted, unformatted, or compressed JavaScript into the editor, choose an indentation size, and format the code without installing additional software.

JavaScript Formatter vs. JavaScript Minifier
A formatter makes JavaScript easier for humans to read by adding structure, indentation, and spacing. A minifier does the opposite: it removes unnecessary whitespace and other characters to reduce file size. Use the Format option when working on code and the Minify option when preparing compact code for delivery.
Who Can Use This JavaScript Formatter?
This tool is useful for web developers, students, programmers, and anyone who needs to inspect or clean up JavaScript code. It can be especially helpful when working with copied, compressed, or poorly indented source code.
