excel.filterable Boolean (default: false)

<div id="grid"></div>
<script>
$("#grid").kendoGrid({
    toolbar: ["excel"],
    excel: {
        filterable: false
    },
    dataSource: {
        transport: {
            read: {
                url: "https://demos.telerik.com/kendo-ui/service/products",
                dataType: "jsonp"
            }
        },
        pageSize: 10
    },
