Hi guys,

I have an asp.net website...

Where i am exporting html data to excel(Jquery Code) but in xls format.

Jquery Code

<script type="text/javascript">
     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) {
             if (!table.nodeType) table = document.getElementById(table)
             var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
             window.location.href = uri + base64(format(template, ctx))

         }
     })()
 </script>

The above code is smoothly working for xls format but i'm looking for xlsx format...

Can any one please help me.

Thanks

First of all, try to export not HTML, but the data used to create HTML. You are using ASP.NET, it means that you have the data and use it to fill in the table, so better use this data.

To write xlsx, I would recommend to use Microsoft Open XML SDK. For example, please see this CodeProject article:
Creating basic Excel workbook with Open XML[^].

Pay attention: Microsoft explains why using Excel interop in server setting is discouraged:
