I'm trying to convert HTML tables to Excel, i have tried with a JavaScript function which converts a simple table to Excel, it is working fine. If I have multiple tables how will I be able to add all the table data into the Excel file. here's what I tried. I've created 2 tables and given table index testTable and testTable1.

How will i pass these 2 table ids to the JavaScript function on click of the button? right now on click of the button only the first table is exported to Excel as I'm passing only 'testTable'. how will i be able to export multiple tables eg: testTable, testTable1 into Excel?

Here's the JavaScript:

<script>

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=""><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>

Here's the HTML part, 

<table id="testTable">
    <thead>
        <tr>
            <th>Name</th>
            <th>ACP</th>
            <th>OEMCP</th>
            <th>Unix<br>
                NT 3.1</th>
            <th>Unix<br>
                NT 3.51</th>
            <th>Unix<br>
                95</th>
        </tr>
    </thead>
</table>
<table id="testTable1">
    <thead>
        <tr>
            <th>Name</th>
            <th>ACP</th>
            <th>OEMCP</th>
            <th>Windows<br>
                NT 3.1</th>
            <th>Windows<br>
                NT 3.51</th>
            <th>Windows<br>
                95</th>
        </tr>
    </thead>
</table>

Please let me know, how this can be done?
Thanks

  • Can't you use web service for this problem. It will also work without postback. – osmanraifgunes Commented Mar 5, 2013 at 12:50

I recommend another Format method. the John Resig micro-template is a very good and simple tool for do what you need. (ejohn microtemplating)

(function(){
  var cache = {};

  this.tmpl = function tmpl(str, data){
    // Figure out if we're getting a template, or if we need to
    // load the template - and be sure to cache the result.
    var fn = !/\W/.test(str) ?
      cache[str] = cache[str] ||
        tmpl(document.getElementById(str).innerHTML) :

      // Generate a reusable function that will serve as a template
      // generator (and which will be cached).
      new Function("obj",
        "var p=[],print=function(){p.push.apply(p,arguments);};" +

        // Introduce the data as local variables using with(){}
        "with(obj){p.push('" +

        // Convert the template into pure JavaScript
        str.replace(/[\r\t\n]/g, " ")
              .split("{{").join("\t")
              .replace(/((^|}})[^\t]*)'/g, "$1\r")
              .replace(/\t=(.*?)}}/g, "',$1,'")
              .split("\t").join("');")
              .split("}}").join("p.push('")
              .split("\r").join("\\'")
              + "');}return p.join('');");

    // Provide some basic currying to the user
    return data ? fn( data ) : fn;
  };
})();

It is very simple to use. This allows not only show variables between HTML but also execute JavaScript code

Your template string need some modification to work with this microtemplate.

{{for(var i=0; i<tables.length;i++){ }}
    <table>
        {{=tables[i]}}
    </table>
{{ } }}

finally only need to select all the tables that appear in your example

document.getElementsByTagName("table");

you can see how it works http://jsfiddle.net/Scipion/P8rpn/1/

create a function and pass the tableID to it

 function passing_id_to_excel(tableID){ 
  var myTableid =
 document.getElementById(tableID) //remaining code }
  1. Add a checkbox for each table. Use javascript to process those that are checked.
  2. In case if you just want to convert every table, you could use $('table').each(function() { do something }).
