in thread get keys from array of hashes

Thanks AppleFritter,
Your method SHOULD work, but I am just now realizing that the ->column_names method itself is not working for me- but using ->print($csv_fh, $columns) does?
UPDATE: This is what I did for me to get it work, I am not sure why the column_names method isn't working for me though..

my $columns = [ keys $AoH_records->[0] ];
$csv->print( $csv_fh, $columns );

You're welcome! tips hat What do you mean by "not working for me"? As far as I can tell, `->column_names()` is not for printing column names to a CSV file; quoting Text::CSV's documentation: `column_names` Set the keys that will be used in the `getline_hr ()` calls. If no keys (column names) are passed, it'll return the current setting. So I'd say `->print()` is the way to go, yes.	[reply]
