G'day reaper9187,

This does what you want:

$ perl -Mstrict -Mwarnings -e '
    my $cols = 4;
    my $re = qr{("(?:[^"\\]++|\\.)*+"\s*,*\s*)}m;
    my $file = do { local $/; <> };
    my @params = $file =~ /$re/g;
    print "$_. ", splice(@params, 0, $cols), "\n" for 1 .. @params / $
+cols;
'
 "123", "DEF123","this 
is
 test","C:\Abhinav\test.jpg"
 "456", "DEF456","this is test","C:\Matt\test.jpg"
 "726", "DEF726","this is test","C:\Matt\test.jpg"
1. "123", "DEF123","this 
is
 test","C:\Abhinav\test.jpg"
 
2. "456", "DEF456","this is test","C:\Matt\test.jpg"
 
3. "726", "DEF726","this is test","C:\Matt\test.jpg"

For the regexp, I've made a very minor addition to what's provided in perlre (search for "match a double-quoted string"). I also used splice to access groups of, what you're calling, parameters.

In future, can I suggest you state something like this in your OP: "I'm aware of Whatever::Module but I want to do this using other_thing because reason_why.". I think that might have saved a lot of questions/answers/updates/etc.
