Hi, maybe this is helpful? (Update: modified as suggested by the master) 

use strict; use warnings;
use Text::CSV_XS 'csv';

my @records = map {
    my %record;
    for ( split "\n" ) {
        my ($key, $val) = split ': ';
        $record{$key} = $record{$key} ? join ', ', $record{$key}, $val
+ : $val;
    };
    \%record;
} split "\n\n", do { local $/; <DATA> };

my @col_names = qw(cn host description env keyWords l sysadm1 sysadm2 
+administratorContactInfo nsHardwarePlatform version);

my @rows = map { my $record = $_; [ map { $record->{$_} || '' } @col_n
+ames ] } @records;

csv( in => \@rows, headers => \@col_names, out => '/tmp/foo.csv' );
