jQuery table2excel Plugin (https://github.com/rainabba/jquery-table2excel)

#Credit for the core table export code concept goes to insin (met on Freenode in #javascript) and core code inspired from https://gist.github.com/insin/1031969

FIRST!!

Thanks for your interest. I haven’t been able to maintain this and found the following project which looks well ahead of this one, so you may want to consider it first: TableExport

DISCLAIMER

This plugin is a hack on a hack. The .xls extension is the only way [some versions] of excel will even open it, and you will get a warning about the contents which can be ignored. The plugin was developed against Chrome and other have contributed code that should allow it to work in Firefox and Safari, but inconsistently since it’s a hack that’s not well supported anywhere but Chrome. I would not use this in public production personally and it was developed for an Intranet application where users are on Chrome and had known versions of Excel installed and the users were educated about the warning. These users also save-as in Excel so that when the files are distributed, the end-users don’t get the warning message.

JQuery Table2 Excel Example Tutorial

Hi Guys

In this tutorial, I will example you how to jquery table2 excel in convert. I am going to share an awesome plug-in for exporting the HTML table data to the excel sheet by a click of a button.

The table contains the <th> tags that define the headings for the table of HTML. The same headers act as the headings in the excel sheet after export. A few options may also be set like tab name in the excel sheet, the file name of excel etc in the jQuery code that I will explain after the demo.

Bellow The Script Used In The Demo:

<script>

    $(function() {

      $("button").click(function(){

        $("#table2excel").table2excel({

          exclude: ".noExl",

          name: "Excel Document Name"

            }); 

      });

    });

</script>

Here this example,the excel export file will download as the demo page loads.

The reason the solution you found on the internet is no working is because of the line that starts var colCount. The variable mytable only has two elements being <thead> and <tbody>. The var colCount line is looking for all the elements within mytable that are <tr>. The best thing you can do is give an id to your <thead> and <tbody> and then grab all the values based on that. Say you had <thead id='headers'> : 

function write_headers_to_excel() 
{
  str="";

  var myTableHead = document.getElementById('headers');
  var rowCount = myTableHead.rows.length;
  var colCount = myTableHead.getElementsByTagName("tr")[0].getElementsByTagName("th").length; 

var ExcelApp = new ActiveXObject("Excel.Application");
var ExcelSheet = new ActiveXObject("Excel.Sheet");
ExcelSheet.Application.Visible = true;

for(var i=0; i<rowCount; i++) 
{   
    for(var j=0; j<colCount; j++) 
    {           
        str= myTableHead.getElementsByTagName("tr")[i].getElementsByTagName("th")[j].innerHTML;
        ExcelSheet.ActiveSheet.Cells(i+1,j+1).Value = str;
    }
}

}

and then do the same thing for the <tbody> tag.

EDIT: I would also highly recommend using jQuery. It would shorten this up to:

function write_to_excel() 
{
 var ExcelApp = new ActiveXObject("Excel.Application");
 var ExcelSheet = new ActiveXObject("Excel.Sheet");
 ExcelSheet.Application.Visible = true; 

  $('th, td').each(function(i){
    ExcelSheet.ActiveSheet.Cells(i+1,i+1).Value = this.innerHTML;
  });
}

Now, of course, this is going to give you some formatting issues but you can work out how you want it formatted in Excel.

EDIT: To answer your question about how to do this for n number of tables, the jQuery will do this already. To do it in raw Javascript, grab all the tables and then alter the function to be able to pass in the table as a parameter. For instance:

var tables = document.getElementsByTagName('table');
for(var i = 0; i < tables.length; i++)
{
  write_headers_to_excel(tables[i]);
  write_bodies_to_excel(tables[i]);
}

Then change the function write_headers_to_excel() to function write_headers_to_excel(table). Then change var myTableHead = document.getElementById('headers'); to var myTableHead = table.getElementsByTagName('thead')[0];. Same with your write_bodies_to_excel() or however you want to set that up.
