If I understand you are interested in something like Rotating an array

update maybe you'll find this useful 

use strict;
use warnings;

my @aoa;
my $row=0;
while (<DATA>){
     chomp;
     push @{$aoa[$row]}, split /\s+/;
     $row++;

}
foreach my $ar (@aoa){
 for my $index (0..$#aoa){
    print +(shift @{$aoa[$index]} || '--')," " ;

 }

}continue{print "\n"}

__DATA__
A1 A2 A3
B1 B2 B3
C1 C2 C3
d1 d2 d3 d4



#OUTPUT

A1 B1 C1 d1 
A2 B2 C2 d2 
A3 B3 C3 d3 
-- -- -- d4
