Dear Perlmonks,

I have written a simple perl script (which works just fine) to open csv file, skip the first two lines of a header and format the columns from: 400;0,34567; to --> 400 0.34567 (change semicolon to space & comma to dot) I would appreciate your ideas on how to improve the following code: 

#!/usr/bin/perl
use strict;
use warnings;
use Text::CSV; 
my $csv = Text::CSV->new;
open (CSV, "<File_name.csv") or die $!;
while (<CSV>) {
    next if (1 .. 2);
    $_ =~ s/\;/ /g;
    $_ =~ s/,/\./g;
    if ($csv->parse($_)) {    
        my @columns = $csv->fields();
            print "@columns\n";
    } 
    else {
                my $err = $csv->error_input;
                print "Failed to parse line: $err";
    }
}
close CSV;

Somehow I have a feeling that this code is not efficient but it works. Is it worth to improve it or just use it as it is? I know it is possible to do this simple character replacement directly in vim using sed or with awk but I want to use Perl instead. Thank you!
