About JavaScript DeObfuscator

JavaScript DeObfuscator PRO (also known as a JS Beautifier) is a developer utility designed to reverse the process of minification. While it cannot restore original variable names if they were mangled during heavy obfuscation, it restores the structure, indentation, and formatting of the code. This makes it possible to read, understand, and debug complex JavaScript files that have been compressed for production use.
