Did exactly what it meant to do!

Worked great. Didn’t allow me to import users with the same email but I got around that with a custom filter:

add_filter(‘pre_user_email’, ‘skip_email_exist’);
function skip_email_exist($user_email){
define( ‘WP_IMPORTING’, ‘SKIP_EMAIL_EXIST’ );
return $user_email;
}

It still throws an error but the importing get’s done.
