I have a "sub trim()" in my Toolbox, so I just call "trim($datapath);".
open (my $filehndl , "<", "$datapath") ||
die ("Can't open .txt file $datapath. Exiting program.\n\n");
Why quote $datapath?
(It isn't in a class with overloaded stringification.)
open my $filehndl , "<", $datapath or die "'$datapath': $!\n";
while (my $line = <$filehdl2>)
{
chomp $line;
my @words = split / /, $line;
my $nr_words = @words;
print "\n$line\n";

If you wouldn't chomp, you wouldn't have to add a "\n".
But then you need to split on " " (to get rid of empty trailings).
while (my $line = <$fh>) {
my @words = split " ", $line;
print $line, "\thas ", scalar(@words), " words.\n";
}
