Parse Razer form after an ajax post

Question

I would like to send the form serialezed with an ajax call to beckend and parse it like with an object.

Right now i send every parameters in this way

var obj = { idSede: idSede, pickupDay: pickupDay, note: note, readyByTime: readyByTime,  closeTime: closeTime };
var json = JSON.stringify(obj);

$.ajax({
            url: "/ajaxCall/ajaxCall?handler=InsertDhlPickup",
            method: "GET",
            data: json,
            success: onSuccess,
            error: onError
        });

But this is not confortable.

This is the serialized form, i would like to send it to backend and parse it like an object

The form is filled with razor model then in ajax post the parameter is called sedeCliente.etc then i can't create an object with the point in the name, to parse it.

Which is the best way to parse the form as an object ?

This is what i would like to have

public JsonResult OnGetInsertDhlPickup(formModel formModel){
       string indirizzo = formModel.Indirizzo;
