Update! got working code that reads csv file and creates hash table. Surprisingly, when i print and check hash size, script displays 13 and prints 13 keys and 13 values. I should have minimum 150 keys/values in hash table. Does anyone take a look and suggest any workarounds!!!

Column_1,Column_2
Name11,In
Name21,Out
Name31,In
Name41,In

use Data::Dumper;
my $infile = file.csv;

sub mainCSV 
{
    open (my $infile1, '<', "$infile") or die "Unable to open $infile:
+ $!";
    my %hash  = (); 
    
    while (my $line = <$infile1>) 
    {
        chomp;
        $line =~ s/\s*\z//;
        my @array = split /,/, $line;
        my $key = shift @array;
        $hash{$key} = \@array;
    }
    
    my $size = scalar keys %hash;   # explicit scalar context
    print "Hash size: $size\n";  # prints Hash size: xx
    
     print Dumper(\%hash);
}
