Hi ,

Below is the method I used to open Excel sheet and save it as CSV file. In Windows 7, Windows Server 2008 R2, the excel process/es is automatically killing itself after processing the excel file/s. In windows Server 2008 Standard Service Pack1, Its going on creating a lot of Excel processes and showing the message 'Microsoft Excel Error - Not enough system resources to display completely.'

Almost near to 200 Excel processes are at Task Manager without killing at that instant and server is hanged./

Below is the code is used to process lot of Excel files.

private static bool SaveExcelCVS(string fileName, string outFile)
        {
            bool success = false;

            try
            {
                Excel.Application xApp = new Excel.Application();
                Excel.Workbook xF1 = xApp.Workbooks.Open(fileName,
                    0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
                    true, false, 0, true, false, false);
                xF1.SaveAs(outFile, Excel.XlFileFormat.xlCSV, "", "", false, false,
                Excel.XlSaveAsAccessMode.xlNoChange, Excel.XlSaveConflictResolution.xlLocalSessionChanges,
                false, false, false, false);
                xF1.Close(false);
                xF1 = null;
                xApp.Quit();
                xApp = null;
                success = true;
            }
            catch
            {
            }
            return success;
        }

Try the following code :

C#

private static bool SaveExcelCVS(string fileName, string outFile)
        {
            bool success = false;
            Excel.Application xApp = new Excel.Application(); 
            try
            {

                Excel.Workbook xF1 = xApp.Workbooks.Open(fileName,
                    0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
                    true, false, 0, true, false, false);
                xF1.SaveAs(outFile, Excel.XlFileFormat.xlCSV, "", "", false, false,
                Excel.XlSaveAsAccessMode.xlNoChange, Excel.XlSaveConflictResolution.xlLocalSessionChanges,
                false, false, false, false);
                xF1.Close(false);
                xF1 = null;

                success = true;
            }
            catch (Exception ex)
            {
                MessageBox.Show("" + ex);
            }
            finally
            {
                xApp.Quit();
                xApp = null;            
            }
            return success;
        }
