<p>I want to download a Excel file. I wrote the data in a html table format and appending to the response. The code is following :</p>

<pre><code>Response.Buffer = false;
Response.Expires = 0;
Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName);
Response.Write(str);
Response.End();
</code></pre>
