Tool to reverse Javascript minify? [duplicate]

Question

Are there any command line scripts and/or online tools that can reverse the effects of minification similar to how Tidy can clean up horrific HTML?

(I'm specifically looking to unminify a minified JavaScript file, so variable renaming might still be an issue.)

Answer 1

You can use this : http://jsbeautifier.org/ But it depends on the minify method you are using, this one only formats the code, it doesn't change variable names, nor uncompress base62 encoding.

edit: in fact it can unpack "packed" scripts (packed with Dean Edward's packer : http://dean.edwards.name/packer/)
