Answer 1

You should not install Excel on the server which is sometimes seen as a solution. One straightforward way is to create a download as a csv file. This will then open in Excel on the client computer. The following method shows you how to do this:

public ActionResult DownloadSelectedReport(int ReportID)
{
    string filename = String.Format("DownloadList{0:yyMMdd}.csv", DateTime.Today);
    MemoryStream memStream = new MemoryStream();
    UnicodeEncoding uniEncoding = new UnicodeEncoding();
    byte[] reportString = uniEncoding.GetBytes(BuildReportAsCSV(ReportID));
    memStream.Write(reportString, 0, reportString.Length);
    return File(memStream.ToArray(), "application/vnd.ms-excel", Server.UrlEncode(filename));
}

Use BuildReportAsCSV(ReportID) to generate your report for downloading.
