Export DataTable to excel

[Nitin]

Is it possible to export google.visualization.DataTable() to excel?

I have data created like :
var data = new google.visualization.DataTable();
data.addColumn()....
data.addRow()....

Now I need to add a button, on click of which the data needs to be
exported in the table format.
Please let me know, where can I find some such kind of example.

Thanks and Regards
Nitin

The way I do this is to
1. save to JSON on the client-side
2. send the JSON to the server via XMLHTTP
3. on server, convert JSON to XML
4. use XSLT to create Excel compatible document and send back to
browser with correct MIME type specified so that it loads into Excel

can you please post a complete example? 

I am afraid that I do not know how to do some of the steps :-(
