I've used the following function for Excel export.

private void ExporttoExcel(DataTable table)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.ClearContent();
        HttpContext.Current.Response.ClearHeaders();
        HttpContext.Current.Response.Buffer = true;
        HttpContext.Current.Response.ContentType = "application/ms-excel";
        HttpContext.Current.Response.Write(@");
        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=Reports.xls");

        HttpContext.Current.Response.Charset = "utf-8";
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("windows-1250");
        //sets font
        HttpContext.Current.Response.Write("<font style="font-size:10.0pt; font-family:Calibri;">");
        HttpContext.Current.Response.Write("<br><br><br>");
        //sets the table border, cell spacing, border color, font of the text, background, foreground, font height
        HttpContext.Current.Response.Write("<table border="1" bgcolor="#ffffff" hold=" />          " bordercolor="#000000" cellspacing="0" cellpadding="0" style="font-size:10.0pt; font-family:Calibri; background:white;"> <tr>");
        ////am getting my grid's column headers
        //int columnscount = g .Columns.Count;

        //for (int j = 0; j < columnscount; j++)
        //{      //write in new column
        //    HttpContext.Current.Response.Write("<td>");
        //    //Get column headers  and make it as bold in excel columns
        //    HttpContext.Current.Response.Write("");
        //    HttpContext.Current.Response.Write(GridView_Result.Columns[j].HeaderText.ToString());
        //    HttpContext.Current.Response.Write("");
        //    HttpContext.Current.Response.Write("</td>");
        //}
        HttpContext.Current.Response.Write("</tr>");
        foreach (DataRow row in table.Rows)
        {//write in new row
            HttpContext.Current.Response.Write("<tr>");
            
            HttpContext.Current.Response.Write("<td>");
            HttpContext.Current.Response.Write(row[0].ToString());
            HttpContext.Current.Response.Write("</td>");
            HttpContext.Current.Response.Write("<td style="width: 2.5px;">");
            HttpContext.Current.Response.Write(row[1].ToString());
            HttpContext.Current.Response.Write("</td>");
            HttpContext.Current.Response.Write("<td>");
            HttpContext.Current.Response.Write(row[2].ToString());
            HttpContext.Current.Response.Write("</td>");
            HttpContext.Current.Response.Write("<td style="width: 2.5px;">");
            HttpContext.Current.Response.Write(row[3].ToString());
            HttpContext.Current.Response.Write("</td>");
            HttpContext.Current.Response.Write("<td>");
            HttpContext.Current.Response.Write(row[4].ToString());
            HttpContext.Current.Response.Write("</td>");
            HttpContext.Current.Response.Write("<td>");
            HttpContext.Current.Response.Write(row[5].ToString());
            HttpContext.Current.Response.Write("</td>");

            HttpContext.Current.Response.Write("</tr>");
        }
        HttpContext.Current.Response.Write("</table>");
        HttpContext.Current.Response.Write("</br></br></br></font>");
        HttpContext.Current.Response.Flush();
        HttpContext.Current.Response.End();
    }
