Frequently Asked Questions

Which languages does this formatter support?

This tool supports HTML, CSS, and JavaScript. Each language has its own specific formatting rules optimized for that syntax.

Is my code kept private?

Yes, completely. All formatting happens locally in your browser. No code is ever transmitted to any server or stored anywhere.

Can I format minified code?

Yes, the formatter works well with minified code. It will add proper line breaks and indentation to make the code readable again.

What's the difference between the indent options?

2 spaces is common in JavaScript projects, 4 spaces is often used in Python and traditional coding styles, and tabs allow each developer to set their preferred viewing width in their editor.

Does the formatter validate my code?

The formatter performs basic syntax checking and will show an error if your code has obvious issues, but it's primarily a formatting tool, not a full validator.
