FormData append json array

I could not do new FormData or insert a json sequence

my Json data:

var data = {
        status: "COMPLETE",
        personName: $('#full_name').val(),
        personPhone: $('#phone_number').cleanVal(),
        personEmail: $('#e_mail').val(),
        referanceFullname: $('#person_full_name').val(),
        referancePhone: $('#person_phone_number').cleanVal(),
        referanceEmail: $('#person_e_mail').val()
      };

How do I attach this to new FormData?
