 string connectionString = ConfigurationManager.ConnectionStrings["connectionstring"].ConnectionString;
        string connectionOleDbString = "";

        DataTable dt = new DataTable();

        if (AsyncFileUpload.HasFile)
        {
            string fileName = Path.GetFileName(AsyncFileUpload.PostedFile.FileName);
            string fileExtension = Path.GetExtension(AsyncFileUpload.PostedFile.FileName);
            string fileLocation = Server.MapPath("~/temp-files/" + fileName);
            AsyncFileUpload.SaveAs(fileLocation);

            if (fileExtension == ".xls")
            {
                connectionOleDbString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 8.0;HDR=YES;IMEX=2\"";
            }
            else if (fileExtension == ".xlsx")
            {
                connectionOleDbString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 12.0;HDR=YES;IMEX=2\"";
            }

            OleDbConnection con = new OleDbConnection(connectionOleDbString);
            OleDbCommand cmd = new OleDbCommand();
            cmd.CommandType = System.Data.CommandType.Text;
            cmd.Connection = con;
            OleDbDataAdapter dAdapter = new OleDbDataAdapter(cmd);
            DataTable dtExcelRecords = new DataTable();
            con.Open();
            DataTable dtExcelSheetName = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
            string getExcelSheetName = dtExcelSheetName.Rows[0]["Table_Name"].ToString().Replace("'", "");
            cmd.CommandText = "SELECT *FROM [" + getExcelSheetName + "A2:H]; SELECT * FROM [" + getExcelSheetName + "A1:A1]";
            dAdapter.SelectCommand = cmd;
            dAdapter.Fill(dt);
            con.Close();

            SqlConnection objConnection = new SqlConnection(connectionString);

            if (objConnection.State == ConnectionState.Open)
            {
                objConnection.Close();
            }

            objConnection.Open();
            SqlBulkCopy objBlkCp = new SqlBulkCopy(objConnection);
     
            objBlkCp.ColumnMappings.Add("city", "city");
            objBlkCp.ColumnMappings.Add("Deal End", "deal_end");
            objBlkCp.ColumnMappings.Add("merchant_id", "merchant_id");
            objBlkCp.ColumnMappings.Add("merchant_name", "merchant_name");
            objBlkCp.ColumnMappings.Add("deal_id", "deal_id");
            objBlkCp.ColumnMappings.Add("voucher_code", "voucher_code");
            objBlkCp.ColumnMappings.Add("u_first_name", "u_first_name");
            objBlkCp.ColumnMappings.Add("u_last_name", "u_last_name");

            objBlkCp.DestinationTableName = "groupon";
            objBlkCp.WriteToServer(dt);
            objConnection.Close();
