I was looking for a similar functionality, thanks Danmero!
But I run into problem when run the code (I reformatted it for my own understanding):

Code:
/usr/gnu/bin/gawk '
BEGIN{
        FS=OFS="|";
        print "ID","Col_Name","Value"
}
!(NR-1){
        split($0,l,FS);
        next
}
{
        for(o=1;++o<NF;)
        {
                split($o,_,",");
                for(O=0;O++<length(_);)
                {
                        print $1,l[o],_[O]
                }
        }
}' aa

The error message is :

gawk: cmd. line:14: (FILENAME=aa FNR=2) fatal: attempt to use array `_' in a scalar context

This is GNU Awk 3.1.1

So, if I understand correctly, gawk does not like length(_) statement? how to work around it?

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
