Ah I see, I do have a column that is unique numbers to each line, so I can use that as my key? 

my $base = $row->{'Base Addr. (Hex)'};
$reghash{$base}{'End Addr.'} = $row->{'End Addr.'};

by this do you mean to say I should be repeating the process so it gets the values for all the 20 columns? Thank you for your input!
