[javascript] Javascript to export html table to Excel

I need to export the html table in my page to an Excel when user clicks 'Export' button. Now, I found a solution here on stack overflow that works in Firefox.

Export dynamic html table to excel in javascript in firefox browser

Now, it doesn't handle special characters like ö,ü,ö which are common in languages we use here so I wanted to ask if anyone knows how I can export them successfully as well without problems?

Here is my code:

 function tabletoExcel(table, name) {
    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]; }); };
        if (!table.nodeType) table = document.getElementById(table);
        var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML };
        window.location.href = uri + base64(format(template, ctx));

}

This question is related to javascript excel

The answer is


For UTF 8 Conversion and Currency Symbol Export Use this:

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 version="1.0" encoding="UTF-8" standalone="yes"?><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))
  }
})()

ShieldUI's export to excel functionality should already support all special chars.
