JavaScript Beautifier

About This Tool

Look, we’ve all been there. You open a JavaScript file and it’s a wall of code—minified, squished, no spaces, no line breaks. It’s like someone took your code and ran it through a paper shredder. That’s where a JavaScript beautifier comes in. It’s not magic, but it’s close. This tool takes that messy, unreadable blob and turns it into something you can actually understand. I’ve used plenty of these over the years. Some are clunky. Some break your code. This one? It just works. No fluff, no ads, no sign-up required. You paste your code, hit beautify, and boom—clean, readable JavaScript. It’s simple, and that’s the point.

FAQ

Will this tool break my code?
Nope. It only reformats—adds spaces, line breaks, and indentation. It doesn’t change variables, functions, or logic. Think of it like cleaning up your room. Everything’s still there, just neater.

Can I use this for TypeScript or JSX?
Not really. This tool is built for plain JavaScript. If you paste in JSX or TypeScript, it might format some parts, but don’t expect perfect results. Stick to .js files for best outcomes.
