To disable quotes, I use
quote_char => undef in the
constructor. Also, binmode after open helps.
#!/usr/bin/perl
use strict;
use warnings;
use Text::CSV_XS;
my $file = 'sample.csv';
my @rows;
my $csv = Text::CSV_XS->new(
{
quote_space => 0,
quote_char => undef,
binary => 1,
auto_diag => 1,
}
) or die "Cannot use CSV: " . Text::CSV_XS->error_diag();
open my $fh, '<:encoding(UTF-8)', $file or die "$!";
binmode $fh, ':encoding(UTF-8)';
while ( my $row = $csv->getline($fh) ) {
push @rows, $row;
}
$csv->eof or $csv->error_diag();
close $fh;
$csv->eof;
open $fh, '>:encoding(UTF-8)', 'new.csv' or die "$!";
binmode $fh, ":encoding(UTF-8)";
$csv->print( $fh, $_ ) for @rows;
close $fh or die "$!";
Output:

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
