Hello everyone, I am trying to replace whitespaces, from my input file, with commas. The challenge I am currently experiencing is that when a selection of the line has no characters it is not recognizing the selection therefore not adding the extra comma in place of the line. What I want my script to do is, add the comma regardless if there is or isn't characters present in the section of the line. Below is what I currently have, where I'm stating that every 3 whitespaces in my input file per line, replace with a comma. Thank you for your time and help, as always everyone is very helpful on here.

use strict;
use warnings;

open (NEW, ">", "OUTPUT_COMMA.txt" ) or die "could not open:$!";
open (FILE, "<", "INPUT.txt") or die "could not open:$!";

    while (my $line = <FILE>)
    {
            $line =~s/\s{3} +/,/g;   
            print NEW $line;

}
close (FILE);
close (NEW)
