NAME

Catmandu::Exporter::CSV - a CSV exporter

SYNOPSIS

# On the command line

$ catmandu convert XSL to CSV < data.xls

$ catmandu convert JSON to CSV --fix myfixes.txt --sep_char ';' < data.json

# Provide a hint to the exporter which fields to export from the JSON
# input. By default the CSV exporter will export the fields that are
# found in the first JSON record.
$ catmandu convert JSON to CSV --fields "id,title,year" < data.json

# In a Perl script

use Catmandu;

my $exporter = Catmandu->exporter('CSV',
            fix => 'myfix.txt',
            quote_char => '"',
            sep_char => ',',
            escape_char => '"' ,
            always_quote => 1,
            header => 1);

$exporter->fields("f1,f2,f3");
$exporter->fields([qw(f1 f2 f3)]);

$exporter->add_many($arrayref);
$exporter->add_many($iterator);
$exporter->add_many(sub { });

$exporter->add($hashref);

printf "exported %d items\n" , $exporter->count;

DESCRIPTION

This Catmandu::Exporter exports items as rows with comma-separated values (CSV). Serialization is based on Text::CSV. A header line with field names will be included if option header is set. See Catmandu::TabularExporter on how to configure the field mapping and column names. Newlines and tabulator values in field values are escaped as \n, \r, and \t.

Hint: by default, the exporter will output all the fields that are found in the first record of the data input. This can be changed by setting the fields option of the exporter.

CONFIGURATION

file

Write output to a local file given by its path or file handle. Alternatively a scalar reference can be passed to write to a string and a code reference can be used to write to a callback function.

fh

Write the output to an IO::Handle. If not specified, Catmandu::Util::io is used to create the output handle from the file argument or by using STDOUT.
