After:
function greet(n) {
    if (n) {
        console.log("Hello, " + n)
    } else {
        console.log("Hello!")
    }
}

Example 2: Minified JSON

Before: {"users":[{"name":"John","age":30},{"name":"Jane","age":25}],"total":2}
After:
{
    "users": [
        {
            "name": "John",
            "age": 30
        },
        {
            "name": "Jane",
            "age": 25
        }
    ],
    "total": 2
}

Example 3: Inline CSS

Before: .container{display:flex;flex-direction:column;padding:20px;}.item{margin:10px;background:#fff;}
After:
.container {
    display: flex;
    flex-direction: column;
    padding: 20px;
}

.item {
    margin: 10px;
    background: #fff;
}

Frequently Asked Questions

What programming languages does this formatter support?

This code formatter supports JavaScript, JSON, HTML, CSS, XML, SQL, Python, and YAML. Each language has specific formatting rules to ensure proper indentation and structure.

Is my code safe when using this formatter?

Yes, absolutely! All code formatting happens directly in your browser. Your code is never sent to any server, ensuring complete privacy and security. You can even use this tool offline.

What's the difference between formatting and minifying?

Formatting adds proper indentation and line breaks for readability, while minifying removes all unnecessary whitespace and comments to reduce file size. Use formatting for development and minifying for production.

Can I customize the indentation style?

Yes! You can choose between 2 spaces, 4 spaces, or tabs for indentation. Select your preference from the dropdown before formatting your code.

Does the formatter validate my code?

For JSON, the formatter will detect and report syntax errors. For other languages, it will attempt to format but may produce unexpected results if the code has syntax errors. Use a dedicated validator for thorough syntax checking.
