string attachment = "attachment; filename=Contacts.xls";
        Response.ClearContent();
        Response.AddHeader("content-disposition", attachment);
        Response.ContentType = "application/ms-excel";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);     

        HtmlForm frm = new HtmlForm();           

        GridView1.Parent.Controls.Add(frm);
        frm.Attributes["runat"] = "server";
        frm.Controls.Add(GridView1);
        frm.RenderControl(htw);        
        Response.Write(sw.ToString());
        Response.End();

The above code exports grid data into excel but not displays cells of excel.

C#

DataTable xlstable = new DataTable(); 
         string xlsFileName = fileName + " Report";
        HttpContext context = HttpContext.Current;
        context.Response.Clear();

        foreach (DataColumn col in xlstable.Columns)
        {
            context.Response.Write(col.ColumnName + "\t");
        }
        context.Response.Write(Environment.NewLine);

        foreach (DataRow row in xlstable.Rows)
        {
            for (int i = 0; i < xlstable.Columns.Count; i++)
            {
                string content = row[i].ToString().Replace("\t", string.Empty) + "\t";
                context.Response.Write(content);
            }
            context.Response.Write(Environment.NewLine);
        }

        context.Response.ContentType = "application/vnd.ms-excel";
        context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + xlsFileName + ".xls");
        try
        {
            context.Response.End();
            //HttpContext.Current.ApplicationInstance.CompleteRequest();
        }
        catch (Exception ex)
        {
            string error = ex.Message.ToString();
        }
        finally
        {
            this.Dispose();
        }
