Visual studio already shipped a utility called undname. For my VS2010 and VS2013 install, it's installed to %VSINSTALL%\vc\bin directory. And for x64 platform, in %VSINSTALL%\vc\amd64\bin directory.

The example usage is:

D:\work\VS2013>undname "?static_x@?1??getX@@YAAAUX@@XZ@4U2@A"
Microsoft (R) C++ Name Undecorator

Undecoration of :- "?static_x@?1??getX@@YAAAUX@@XZ@4U2@A"
is :- "struct X `struct X & __cdecl getX(void)'::`2'::static_x"

Another way to get the demangled name is use /FAsc /Faoutput.asm compiler option, which will produce the assembly list, in which each mangled name is commented with it's demangled name. See This link for reference.
