Perl script to modify csv file
Hi Friends,

I want to convert a csv file into a ordinary .txt file. I am able to convert but I want the output to look as shown below in the .txt file

Code:
table findhost=
{
{"xyz","abc"},
{"rxz","mmz"},
{"vrr","nnz"},
}
default={"NONE"}

My current perl script

Code:
#!/usr/bin/env perl
use strict;
use warnings;
use Text::CSV;

my @rows;

# Read the CSV file
{
    my $csv = Text::CSV->new()
        or die "Cannot use Text::CSV ($!)";
    my $file = "data.csv";
    open my $fh, '<', $file
        or die "Cannot open $file ($!)";

    while (my $row = $csv->getline($fh))
    {
        push @rows, $row;
    }
    $csv->eof or $csv->error_diag();

    close $fh
        or die "Failed to close $file ($!)";
}

# Munge the data
{
    foreach my $row (@rows)
    {
        foreach my $col (@{$row})
        {
            $col = uc($col);
        }
        print "\n";
    }
}

# Write the data
{
    my $csv = Text::CSV->new()
        or die "Cannot use Text::CSV ($!)";
    my $file = "output.csv";
    open my $fh, '>', $file
        or die "Cannot open $file ($!)";
    $csv->eol("\n");
    foreach my $row (@rows)
    {

        $csv->print($fh, \@{$row})
            or die "Failed to write $file ($!)";
    }
    close $fh
        or die "Failed to close $file ($!)";
}

The output of this script is shown below:

Code:
XYZ,ABC
RXZ,MMZ
VRR,NNZ

I want to make the output to look as shown below:

Code:
table findhost=
{
{"xyz","abc"},
{"rxz","mmz"},
{"vrr","nnz"},
}
default={"NONE"}

My CSV looks as shown below:

Code:
xyz,"abc"
rxz,mmz
vrr,"nnz"

If double quotes are not there in the CSV file I need to ensure that I put the double quotes.

Can anyone tell where I should I modify.

Thanks,
Din
