Would you mind being more specific? Can you tell us which module you are using and show a few lines of the code where you use it?

    #!/usr/bin/env perl use Text::CSV; my $csv = Text::CSV->new(); open(my $in_fh, "<", "") or die "please create your temporary file: $!"; my @rows = (); + # keeps the count of rows in txt input file while( my $line = <$in_fh> ){ + # copies the line from our input chomp $line; push @rows, [ split m{ , }msx, $line ]; + } close $in_fh or die "could not close $in_file: $!\n"; $csv->eol( "\n" ); + # after each line it gives a new line command print " Please enter the name of your csv file in which you will make +modifications "; print "\n"; my $out_file = <>; chomp $out_file; open my $out_fh, '>', $out_file or die "could not open $out_file: $!\n +"; for my $row ( @rows ){ $csv->print( $out_fh, $row ) or die "could not print to $out_file: $ +!\n"; } close $out_fh or die "could not close $out_file: $!\n";
    This is what I am doing

      You are using the module only for the generation of CSV, not for the parsing. Start by writing your parsing code safer:

      use Text::CSV; my $csv = Text::CSV->new ({ binary => 1, auto_diag => 1 }); open my $in_fh, "<", "" or die "please create your temporary file: $!"; my @rows = (); while (my $row = $csv->getline ($in_fh)) { push @rows, $row; }

      I am sure I posted the same answer in this thread

        Hey thanks for helping

        but i made the changes , but still the problem continues

      So you are reading from a file, split on comma, then write it into another file. I would expect that there are no commas in the data you are writing to the new file as all commas are gone due to the splitting.

      Probably some example would be useful like an input line and the corresponding output line that has double quotes in front of every word.

        yes pretty much , but what I have done is replaced the commas of text file to a delimiter as ;; , so that i can split it using ;; , and even if there is a comma in file it would not affect it

        input looks like 50;; C,nt ;; ;;8;; 1;; ds;; 1;; a;; 1;; 0;; 0;; ;; ;; ;; output looks like " 50"," C ,nt "," ",8," 1","ds","1"," Va"," 1"," 0"," 0"," "," "," " and I just want these " " to get omitted

         push @rows, [ split m{ ;; }msx, $line ];   I have done this in the code
