Check this out    I just got this working and it seems exactly what you are trying to do as well   2 functions  One to select the table and copy it to the clipboard  and the second writes it to excel en masse  Just call write to excel   and put in your table id  or modify it to take it as an argument      function selectElementContents el            var body   document body  range  sel          if  document createRange  amp  amp  window getSelection                range   document createRange                sel   window getSelection                sel removeAllRanges                try                   range selectNodeContents el                   sel addRange range                 catch  e                    range selectNode el                   sel addRange range                           else if  body createTextRange                range   body createTextRange                range moveToElementText el               range select                      range execCommand  Copy           function write to excel      var tableID    AllItems   selectElementContents  document getElementById tableID      var excel   new ActiveXObject  Excel Application       excel Application Visible   true   var wb excel WorkBooks Add    var ws wb Sheets  Sheet1    ws Cells 1 1  Select  ws Paste  ws DrawingObjects Delete  ws Range  A1   Select  excel Application Visible   true       Heavily influenced from  Select a complete table with Javascript  to be copied to clipboard

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  lt thead gt  and  lt tbody gt   The var colCount line is looking for all the elements within mytable that are  lt tr gt   The best thing you can do is give an id to your  lt thead gt  and  lt tbody gt  and then grab all the values based on that  Say you had  lt thead id  headers  gt      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 lt rowCount  i              for var j 0  j lt 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  lt tbody gt  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  lt  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

I think you can also think of alternative architectures  Sometimes something can be done in another way much more easier  If the producer of HTML file is you  then you can write an HTTP handler to create an Excel document on the server  which is much more easier than in JavaScript  and send a file to the client  If you receive that HTML file from somewhere  like an HTML version of a report   then you still can use a server side language like C  or PHP to create the Excel file still very easily  I mean  you may have other ways too

I would suggest using a different approach  Add a button on the webpage that will copy the content of the table to the clipboard  with TAB chars between columns and newlines between rows  This way the  paste  function in Excel should work correctly and your web application will also work with many browsers and on many operating systems  linux  mac  mobile  and users will be able to use the data also with other spreadsheets or word processing programs   The only tricky part is to copy to the clipboard because many browsers are security obsessed on this  A solution is to prepare the data already selected in a textarea  and show it to the user in a modal dialog box where you tell the user to copy the text  some will need to type Ctrl-C  others Command-c  others will use a  long touch  or a popup menu    It would be nicer to have a standard copy-to-clipboard function that possibly requests a user confirmation    but this is not the case  unfortunately
