I want to export data datagridview to excel for using this code:- Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application(); // creating new WorkBook within Excel application Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing); // creating new Excelsheet in workbook Microsoft.Office.Interop.Excel._Worksheet worksheet = null; // see the excel sheet behind the program app.Visible = true; // get the reference of first sheet. By default its name is Sheet1. // store its reference to worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets["Sheet1"]; worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet; // changing the name of active sheet worksheet.Name = "UUSProducts"; // storing header part in Excel for (int i = 1; i { worksheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText; } // storing Each row and column value to excel sheet for (int i = 0; i { for (int j = 0; j { worksheet.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString(); } } // save the application workbook.SaveAs("c:\UUSProducts.xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing); // Exit from the application app.Quit(); but this code successfully run but when i importing this excel file so getting exception: "External table is not in the expected format" i am using .xls format for excel. So, how can we remove this exception? Please help me. Ankit Agarwal Softeware Engineer

Column header added... Note : The table variable should be your data source of the gridview control. Or you can use gridview.DataSource(with type casting). string temp = string.Empty; foreach (DataColumn colx in table.Columns) { temp = temp + colx.ColumnName + "|"; } temp = temp + Environment.NewLine; foreach (DataRow item in table.Rows) { foreach(string str in item.ItemArray) { temp = temp + str + "|"; } temp = temp + Environment.NewLine; } System.IO.File.AppendAllText(@"c:	emp.psv",temp);

Without header.... string temp = string.Empty; foreach (DataRow item in table.Rows) { foreach(string str in item.ItemArray) { temp = temp + str + "|"; } temp = temp + Environment.NewLine; } System.IO.File.AppendAllText(@"c:	emp.psv",temp);
