JavaScript Beautifier
What this does
Reformats compressed JavaScript into readable code: line breaks after statements, indentation by block, spaces around operators. Variable names are not restored — for that see the Deobfuscator.
When to use it
- Reading a library or a site script that shipped minified.
- Debugging when the source map is missing.
Good to know
Formatting is purely cosmetic; the code behaves identically.
