For me, I had a dropdown selection for some page options and needed to add a body class for each selection for styling.

add_filter('body_class', 'add_acf_body_class');
function add_acf_body_class($class) {
    $field = get_field_object('page_width', get_queried_object_id());
    $value = $field['value'];
    $label = str_replace( '_', '-', $value ); //Change _ to -
    $class[] = $label;

    return $class;
}
