Before the cell insertion above you have to add a worksheet

Excel.Application excelApplication = new Excel.Application();
Excel.Workbook excelWorkBook = excelApplication.Workbooks.Add();
Excel.Worksheet wkSheetData = excelWorkBook.ActiveSheet;
excelApplication.Cells[5, 2] = "TextField";

I hope this helps
