use Data::Dumper;

## your @AoA here ...

my @results = map {
  grep(/\n/, @$_)
    ? map([split "\n"], @$_)
    : $_
} @AoA;

print Dumper( \@results );

If you want to update the original data just change the my @results = to @AoA =. Also you could use Scalar::Util::first there instead of grep if you're looking for an optimal solution.
