From wc_get_order() to REST API data - WooCommerce

Question

Comparing the data returned by wc_get_order($order)->get_data() to the data returned by the wc()->api->get_endpoint_data('/wc/v3/orders/' . $order); REST endpoint, the data is the same, except for that in the first case, for some keys the data is an object instead of a formatted piece of information.

E.g. [date_created] => 2022-04-13T10:11:52 returned by REST, is like this

[date_created] => WC_DateTime Object
    (
        [utc_offset:protected] => 7200
        [date] => 2022-04-13 08:11:52.000000
        [timezone_type] => 1
        [timezone] => +00:00
    )

in the data returned by wc_get_order()...

What's the code that "flattens" the data converting it to the one returned by the REST API?
