Free JavaScript Beautifier

Writing JavaScript code is easy, but reading messy or minified code can quickly become difficult. Long lines, missing spaces, and poor formatting make it harder to understand what the code is doing. That is why we created the LGA JavaScript beautifier.

Before we explain how to use the tool, let's first understand what a JS beautifier is.

What Is a JavaScript Beautifier?

A JS beautifier is a tool that reformats JavaScript code into a clean and organized layout without changing how the code works. It adds proper indentation, spaces, and line breaks to make the code easier to read and understand.

Our LGA JS beautifier gives you control over indentation size, brace style, and spacing preferences while keeping your original code logic unchanged.

Now that you know what this tool does, let's learn how to use it.

Using our JavaScript beautifier takes only a few seconds. Follow these simple steps:

Step 1: Paste Your JavaScript Code: Copy your JavaScript code and paste it into the JavaScript Input box. You can paste messy, unformatted, or minified code.

Step 2: Choose the Indent Size: Select how you want the formatted code to be indented. You can choose options like 2 spaces, 4 spaces, or tabs based on your coding style or project requirements. Proper indentation makes your JavaScript code cleaner and much easier to read.

Step 3: Choose the Brace Style: Select the brace style you want to use for your formatted code. You can choose options like Collapse, Expand, or End-Expand. Each style changes the position of opening braces to match your preferred coding standard or team guidelines.

Step 4: Choose Whether to Add Spaces Inside Parentheses: If you prefer spaces inside function parentheses, simply enable this option. If not, leave it disabled. This lets you format the code according to your preferred coding style.

Step 5: Click the Beautify Button: Click the Beautify button to format your JavaScript code instantly. The tool processes your code and displays the clean, organized version in the output box.

Step 6: Review the Beautified Code: Check the formatted output to make sure the indentation, spacing, and brace style match your preferences before using the code in your project.

Step 7: Copy the Formatted Code: Click the Copy Code button to copy the beautified JavaScript code to your clipboard. You can then paste it directly into your editor or project.

Step 8: Load an Example: If you want to see how the tool works before using your own code, click Load Example. The tool will insert a sample JavaScript snippet that you can beautify instantly.

Step 9: Clear the Input: Click the Clear button whenever you want to remove the current JavaScript code from the input box and start with new code.

Step 10: Reset the Tool: Use the Reset button to restore the tool to its default settings. This clears the input, output, and formatting options so you can begin a new session.
