Export html table to Excel javascript function special characters changed

Question

function generateexcel(tableid) {
  var table= document.getElementById(tableid);
  var html = ta         


        

Answer 1

In my case I use generateexcel function previously posted, just adding Capital letters of special characters in order to make it work

    function generateexcel(tableid) {
      var table= document.getElementById(tableid);
      var html = table.outerHTML;
      while (html.indexOf('á') != -1) html = html.replace('á', 'á');
      while (html.indexOf('Á') != -1) html = html.replace('Á', 'Á');
      while (html.indexOf('é') != -1) html = html.replace('é', 'é');
      while (html.indexOf('É') != -1) html = html.replace('É', 'É');
      while (html.indexOf('í') != -1) html = html.replace('í', 'í');
      while (html.indexOf('Í') != -1) html = html.replace('Í', 'Í');
      while (html.indexOf('ó') != -1) html = html.replace('ó', 'ó');
      while (html.indexOf('Ó') != -1) html = html.replace('Ó', 'Ó');
      while (html.indexOf('ú') != -1) html = html.replace('ú', 'ú');
      while (html.indexOf('Ú') != -1) html = html.replace('Ú', 'Ú');
      while (html.indexOf('º') != -1) html = html.replace('º', 'º');
      while (html.indexOf('ñ') != -1) html = html.replace('ñ', 'ñ'); 
      while (html.indexOf('Ñ') != -1) html = html.replace('Ñ', 'Ñ');  

  window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));
}

Hope it helps...
