        function convertToCsv(fName, rows) {
        var csv = '';
        for (var i = 0; i < rows.length; i++) {
            var row = rows[i];
            for (var j = 0; j < row.length; j++) {
                var val = row[j] === null ? '' : row[j].toString();
                val = val.replace(/\t/gi, " ");
                if (j > 0)
                    csv += '\t';
                csv += val;
            }
            csv += '\n';
        }

        // for UTF-16
        var cCode, bArr = [];
        bArr.push(255, 254);
        for (var i = 0; i < csv.length; ++i) {
            cCode = csv.charCodeAt(i);
            bArr.push(cCode & 0xff);
            bArr.push(cCode / 256 >>> 0);
        }

        var blob = new Blob([new Uint8Array(bArr)], { type: 'text/csv;charset=UTF-16LE;' });
        if (navigator.msSaveBlob) {
            navigator.msSaveBlob(blob, fName);
        } else {
            var link = document.createElement("a");
            if (link.download !== undefined) {
                var url = window.URL.createObjectURL(blob);
                link.setAttribute("href", url);
                link.setAttribute("download", fName);
                link.style.visibility = 'hidden';
                document.body.appendChild(link);
                link.click();
                document.body.removeChild(link);
                window.URL.revokeObjectURL(url);
            }
