Как экспортировать datagridview в шаблон excel

---

Как можно экспортировать datagridview(55items) в шаблон excel с ограниченными строками(30rows) и открыть другую копию шаблона как страницу 2 для баланса(25items) datagridview.

Что я уже пробовал:

<pre>private void button1_Click_1(object sender, EventArgs e)
        {
            Excel.Application xlApp;
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;
            
            xlApp = new Excel.Application();
            string filePath = @"C:\CedarData\masterquote.xltx";
            xlWorkBook = xlApp.Workbooks.Add(filePath);
            
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            //int i = 1;
            //int j = 1;

            string datestr = DateTime.Now.ToShortDateString();
            //string colName = dataGridView1.Columns[j].HeaderText;
            string filename = @"C:\CedarData\CedarQuotes\Quote_" + txtName.Text.Replace(" ", "") + "_" + datestr + ".xls";
            string quote = txtName.Text.Replace(" ", "") + "_" + datestr;
            string salesman = txtEmail.Text.ToUpper();
            string customer = txtName.Text.ToUpper();

            // Storing Each row and column value to excel sheet   
            for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
            {

                for (int j = 0; j < dataGridView1.Columns.Count; j++)
                {
                    
                        xlWorkSheet.Cells[i + 19, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
                       // xlWorkSheet.HPageBreaks.Add(xlWorkSheet.get_Range("A49", "J49"));
                    }
                    
                    xlWorkSheet.get_Range("C10", "E10").Value2 = salesman;
                    xlWorkSheet.get_Range("C12", "E12").Value2 = customer;
                    xlWorkSheet.get_Range("C12", "E12").Font.Bold = true;
                    xlWorkSheet.get_Range("C12", "E12").Font.Bold = true;
                    xlWorkSheet.get_Range("H12", "I12").Value2 = DateTime.Now;
                    xlWorkSheet.get_Range("H10", "I10").Value2 = quote;

                }

            
             
            xlWorkBook.SaveAs(filename, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, 

Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
            xlWorkBook.Close(true, misValue, misValue);
            xlApp.Quit();

            releaseObject(xlWorkSheet);
            releaseObject(xlWorkBook);
            releaseObject(xlApp);

            MessageBox.Show("Excel file created , you can find the file c:\\quote.xls");
        }
