I didn't understand a single word, but it seem you need something as following
C#
var excelApp = new ApplicationClass {Visible = false}; //use Application for .NET 4.0 and later

var excelWorkbooks = excelApp.Workbooks.Open("yourfilepath");
var excelWorkSheet = (Worksheet) excelWorkbooks.Sheets[yourWorkSheetNumber]; //be sure to cast to  Workseet explictly
excelWorkSheet.Cells[row, column] = yourvalue;
excelWorkbooks.Save(); //calling excelApp.Save(); would cause an exception
excelApp.Quit();
Marshal.ReleaseComObject(excelWorkSheet); //release COM-object to terminate processes
Marshal.ReleaseComObject(excelWorkbooks);
GC.Collect();
GC.WaitForPendingFinalizers();

This code doesn't even compile.
Extra closing bracket ) on line 2
_excelWorkbooks has not been declared on lines 3 and 8(lose the underscore)
Why on earth force the garbage collection?
Where is the for loop the OP asked for?

Sure it doesn't complile. Variables like 'row', 'column' etc aren't defined. That is the way examples are.
Look through stackoverflow. There are loads of issues with Interop.Excel, where garabage collection needs to be forced to force termination of Excel proccess. You might not notice, when you work with 1 file, but when you work with 15 different files it will eat out all of your memory.
About loop. Frankly speaking I just can't figure out where does he want to put it.
