Frequently asked questions

Does it fix my code or just format it?＋

It reformats indentation and spacing for readability. It doesn't lint your logic or rename anything.

Can it un-minify JavaScript?＋

Yes — it re-indents minified or one-line JavaScript so you can read it, though original variable names can't be recovered.

Is my code private?＋

Yes — formatting happens in your browser.
