        ExcelWorkbook workbook = new ExcelWorkb

You may be better off using a jagged array instead of a multi-dimensional array. I have had more success getting a jagged array working. Also Explosion Pills is right, the dataType is the type of the response. I was able to get this working using a json request by using JSON.stringify on the data and specifying the contentType of application\json:

Controller:

    public ActionResult Test(string[][] fields, string workbookName)
    {
        var cr = new JsonResult();
        cr.Data = fields;
        return cr;
    }

JS:

var arguments = {};

arguments.fields = new Array(3);
arguments.fields[0] = new Array(3);
arguments.fields[1] = new Array(3);
arguments.fields[2] = new Array(3);

arguments.fields[0][0] = "hello";

arguments.workbookName = "test";

//Populate arrayOfValues 
$.ajax({
    type: "POST",
    url: '/Home/Test',
    dataType: "json",
    contentType: 'application/json',
    traditional: true,
    data: JSON.stringify(arguments),
    success: function (data) {
        alert(data);
    }
});
