I searched on google.

i want to export data to excel 2007(xlsx) format as it is having 80,000 records.

C#

GridView GridView1 = new GridView();
                GridView1.DataSource = ((DataTable)Session["EXECUTIVE_ACT_RPT"]);
                GridView1.DataBind();
                Response.Clear();
                Response.Buffer = true;
                Response.AddHeader("Content-Disposition", "attachment; filename=abc.xlsx");
                //Choose one of these: as the contentType
                //Excel 2003 : "application/vnd.ms-excel"
                //Excel 2007 : "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" 

                Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

                System.IO.StringWriter writer = new System.IO.StringWriter();

                System.Web.UI.HtmlTextWriter html = new System.Web.UI.HtmlTextWriter(writer);
                GridView1.RenderControl(html);

                Response.Write(writer);

                Response.End();

when i open the file it shows that the file is not valid.
it says :
"either corrupted or the extension is not valid"

i dont want to export it in xls format.

protected void btnExcel_Click(object sender, ImageClickEventArgs e)
{
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Customers.xlsx"));
Response.ContentType = "application/vnd.xls"
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvdetails.AllowPaging = false;
gvdetails.DataBind();
//Change the Header Row back to white color
gvdetails.HeaderRow.Style.Add("background-color", "#FFFFFF");
//Applying stlye to gridview header cells
for (int i = 0; i < gvdetails.HeaderRow.Cells.Count; i++)
{
gvdetails.HeaderRow.Cells[i].Style.Add("background-color", "#507CD1");
}

//This loop is used to apply stlye to cells based on particular row
