Re^3: hashref to arrayref

I'm not clear on what you want the array to contain. Just the bottom-level values? If I understand correctly, your structure looks like

%errors=(key1 => { date => 'some date',
                   time => 'some time',
                 },
         key2 => { date => 'some other date',
                   time => 'some other time',
                 },
         ...
         );

so when you read it in list context, you get a list of keys and hashrefs. What exactly are you trying to get back?

I ended up doing the following to get what I needed: `my @values = map { ( $errors{$_}{'date'}, $errors{$_}{'time'}, $errors{$_}{'cnt' +}, $_ ) } keys %errors; my $value_ref = [@values]; my $file_ref = new IO::File "> csvoutput.csv"; my $status = $csv->print ($file_ref, $value_ref)` [download] The problem was that in my original code I was returning array references to the elements in the @values array. I simply had to remove the brackets and all is good. Thanks again for all your time!	[reply] [d/l]

my @values = map {
        (  $errors{$_}{'date'}, $errors{$_}{'time'}, $errors{$_}{'cnt'
+}, $_ )
    } keys %errors;
my $value_ref = [@values];
my $file_ref = new IO::File "> csvoutput.csv";
my $status = $csv->print ($file_ref, $value_ref)
