Export pdf file using ajax in MVC C #

I would like to know how to export an excel file using ajax, I have tried in the following way, but it does not work:

$("#ajax_loader").css("display", "");
var formato = "PDF";

//window.location.href = url;
//$("#ajax_loader").hide();
var fd = new FormData();
fd.append("format", formato);
fd.append("nombreObra", $('#nombre_obra').val());
$.ajax({
type: "POST",
url: '<%= Url.Action("Export", "Obras")%>',
data: fd,
DataType: 'json',
contentType: false,
processData: false,
success: function (data) {
$("#ajax_loader").hide();
}
});
});


If anyone has any ideas, I would greatly appreciate it. Greetings.
