After that go to COM tab and select and add Microsoft Excel 12.0 object library. Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application(); Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing); Microsoft.Office.Interop.Excel._Worksheet worksheet = null; app.Visible = true; try { worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets[Sheet1]; worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet; worksheet.Name = Exported from DataGridView; for (int i = 1; i { worksheet.Cells[1 i] = DataGridView1.Columns[i - 1].HeaderText; } for (int i = 0; i { for (int j = 0; j { worksheet.Cells[i + 2 j + 1] = DataGridView1.Rows[i].Cells[j].Value.ToString(); } } string fileName = String.Empty; saveFileExcel.Filter = Excel files |*.xls|All files (*.*)|*.*; saveFileExcel.FilterIndex = 2; saveFileExcel.RestoreDirectory = true; if (saveFileExcel.ShowDialog() == DialogResult.OK) { fileName = saveFileExcel.FileName; workbook.SaveAs(fileName Type.Missing Type.Missing Type.Missing Type.Missing Type.Missing Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive Type.Missing Type.Missing Type.Missing Type.Missing Type.Missing); } else return; } catch (System.Exception ex) { MessageBox.Show(ex.Message); } finally { app.Quit(); workbook = null; app = null; } } } } Thanks If this post helps you mark it as answer

@Satyapriya: Thank you! It worked. Just one thing this line was missing. SaveFileDialog saveFileExcel = new SaveFileDialog();
