In Perl, you can use the Data::Dumper module to dump data structures into a string. Here’s an example:

use Data::Dumper;

my $data = { 
    name => 'John Doe',
    age => 35,
    hobbies => ['reading', 'swimming', 'traveling'],
};

my $string = Dumper($data);
print $string;

The output of this code will be a string representation of the data structure:

$VAR1 = {
          'name' => 'John Doe',
          'hobbies' => [
                         'reading',
                         'swimming',
                         'traveling'
                       ],
          'age' => 35
        };

You can also use the Dumper() function to dump other types of data structures, such as arrays or scalars.
