JS Beautifier

Beautifying JavaScript makes opaque code easier to examine, especially when you are debugging a production snippet, reviewing a third-party embed, or comparing an older script with a newer one. Clear indentation often reveals control flow problems faster than search alone.

The tool focuses on formatting, not rewriting behavior. Variable names, bundler wrappers, and obfuscated patterns may still be difficult to understand, but a readable layout gives you a better starting point for inspection.
