Hi,

The spreadsheet modules have code to do this for you 

use Data::Dump qw/ dd /;
use Spreadsheet::Read qw( cr2cell );
for my $pair (  [0,0],
                [1,1],
                [12,12],
                [25,25],
                [26,26],
                [66,66],
                [666,666],
                [6666,6666],
            ) {
    dd( cr2cell( @$pair ) , @$pair );
}
__END__
("", 0, 0)
("A1", 1, 1)
("L12", 12, 12)
("Y25", 25, 25)
("Z26", 26, 26)
("BN66", 66, 66)
("YP666", 666, 666)
