Creating Excel file in C#

Posted By: admin On:7/13/2010 5:52:53 AM in:Source Codes Category:CSharp Hits:3937
The following section explains how to create an Excel file programmatically using C#.


Before you create an Excel file in C# , you have to add the Microsoft Excel 12.0 Object Library to you project.

Source Code

private void CreateExcelFile(object sender, EventArgs e)
            Excel.Application xlApp ;
            Excel.Workbook xlWorkBook ;
            Excel.Worksheet xlWorkSheet ;
            object misValue = System.Reflection.Missing.Value;

            xlApp = new Excel.ApplicationClass();
            xlWorkBook = xlApp.Workbooks.Add(misValue);

            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
            xlWorkSheet.Cells[1, 1] = "";

            xlWorkBook.SaveAs("csharp-Excel.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
            xlWorkBook.Close(true, misValue, misValue);


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

        private void releaseObject(object obj)
                obj = null;
            catch (Exception ex)
                obj = null;
                MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
