Excell to Acces Data Transfer

Question

I just want to get the lines with tax ID "78898989898" and I want the numbers to be transferred in "0.00" format

 

string patchmdb;
        OleDbConnection cnEMP = new OleDbConnection();

        private void button1_Click(object sender, EventArgs e)
        {

            string patchxls = Application.StartupPath + "\\taxlist.xls";

            DataTable dtEMP = new DataTable();
            string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + patchxls + "; Extended Properties='Excel 8.0;HDR=No;'";
            using (OleDbConnection cnEMP = new OleDbConnection(ConnectionString.ToString()))
            {
                cnEMP.Open();
                using (OleDbCommand cmdEMP = new OleDbCommand("SELECT * FROM [tax$C5:M]", cnEMP))
                {
                    using (OleDbDataReader drEMP = cmdEMP.ExecuteReader())
                    {
                        dtEMP.Load(drEMP);
                        dataGridView1.DataSource = dtEMP;
                    }
                }
                cnEMP.Close();
            }

            foreach (DataGridViewRow EMPRow in dataGridView1.Rows)
            {
                patchmdb = Application.StartupPath + "\\data.mdb";

                cnEMP.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + patchmdb;
                cnEMP.Open();
                OleDbCommand cmdEMP = new OleDbCommand();
                cmdEMP.Connection = cnEMP;


                string qryEMP = "INSERT INTO bill([a], [b], [c], [d], [e], [f], [g], [h], [j], [k]) ";
                qryEMP = qryEMP + "Values('" + EMPRow.Cells[0].Value + "','" + EMPRow.Cells[2].Value + "','" + EMPRow.Cells[7].Value + "','" + EMPRow.Cells[8].Value + "','" + null + "','" + null + "','" + null + "','" + null + "','" + null + "','" + null + "')";
                cmdEMP.CommandText = qryEMP;
                cmdEMP.CommandType = CommandType.Text;
                cmdEMP.ExecuteNonQuery();
                cnEMP.Close();
            }

            OleDbConnection connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + patchmdb);
            connection.Open();

            OleDbCommand kdvsil = new OleDbCommand("DELETE FROM bill WHERE Len(Trim(a &''))=0;", connection);
            kdvsil.ExecuteNonQuery();
            connection.Close();
        }
