Thanks for the reply and apologies - I was not clear on this.

1. I've looked over @http://demos.telerik.com/kendo-ui/spreadsheet/server-side-import-export and it works if you're an end user. I want to be able to programmatically save Excel to a folder on server (e.g. ~/App_Data) in my controller. One of my goals here would be to send that saved Excel file from the server to different folks or processes. 

2. I've also looked @ http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/spreadsheet/spreadsheet-processing and it does not work for me (console logs, breakpoints, shows nothing). Here is my code:

$("#save").click(function () {
        var spreadsheet = $("#ks_spreadsheet").data("kendoSpreadsheet");
        
        $.ajax({
            url: "@Url.Action("PostDealClientData", "DealClientKS")",
            data: JSON.stringify(spreadsheet.toJSON()),
            contentType: "application/json",
            type: "POST"
        });
    });

[HttpPost]
        public ActionResult PostDealClientData(Telerik.Web.Spreadsheet.Workbook workbook)
        {
            var savePath = Server.MapPath("~/ExcelSave/DealClient.xlsx");
            workbook.Save("~/ExcelSave/Workbook.xlsx");

            return new EmptyResult();
        }
