Generate an Excel XML document in Asp.net MVC Web Site

I have an ASP.Net MVC site that generates a Microsoft Excel 2003 XML formatted spreadsheet. The spreadsheet looks good, the controller and views both work, but the file won't open in Excel. It opens in the browser because it is an XML document.

I tried changing the ContentType to be the Excel XLS format (application/excel) and that made Excel open the file but it gives a warning message that the file is an XML document, not an XLS document.

How do you make an Excel XML document open in Excel from a web site?

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %><%  
this.Context.Response.Clear();  
this.Context.Response.AddHeader("content-disposition", "attachment;filename=State_Report_" + this.ViewData["State"] + ".xml");  
this.Context.Response.Charset = "";  
this.Context.Response.Cache.SetCacheability(HttpCacheability.NoCache);  
this.Context.Response.ContentType = "application/excel";  
%><?xml version="1.0"?>  
<?mso-application progid="Excel.Sheet"?>  
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"  
  xmlns:o="urn:schemas-microsoft-com:office:office"  
  xmlns:x="urn:schemas-microsoft-com:office:excel"  
  xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"  
  xmlns:html="http://www.w3.org/TR/REC-html40">

Try with 

Response.ContentType = "application/vnd.ms-excel"

And keep the .XML extension.

Your problem may be in using the file extension .xml, which you're adding in your header. My code that does this same thing does not have a file extension at all.

You might try dropping that .xml extension, or changing it to .xls or .csv.
