    I have called the tableToexcel function on button click like as below and it is working fine in firefix.

    <a id="dlink"  style="display:none;"></a>

    var tableToExcel = (function () {
            var uri = 'data:application/vnd.ms-excel;base64,'
            , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
            , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
            , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
            return function (table, name, filename) {
                if (!table.nodeType) table = document.getElementById(table)
                var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }

                document.getElementById("dlink").href = uri + base64(format(template, ctx));
                document.getElementById("dlink").download = filename;
                document.getElementById("dlink").click();

            }
        })();

    excel sheet has got a character limit for 32767 characters similar to that of an excel cell.

    Most likely you've hit the 2 MB URL limit in Chrome. You can read about it here - issue link. I suggest you try your app in Firefox, if it works, then that is the issue.
