Even though I am using the below code, the EXCEL.EXE is still running in the back , so not able to open and modify the Excel sheet.

Please help me ............. Need your quick response.

In my case I am opening the same Excel again and again in a loop and everytime I am trying to edit the sheet.

Hi,

Try this ! .

excelApp.Quit();
Marshal.ReleaseComObject (excelWB);
Marshal.ReleaseComObject (excelApp);
excelApp = null;

This worked for a project which I was working on.

Press CheckBox if you feel this is correct answer !
