productType.insert();

You probably translated the error, the exact error when I test this is:

SysExcelWorksheet object not initialized.

This is probably because on the following line you are trying to retrieve the 4th worksheet of the excel, but your excel file has less:

worksheet = worksheets.itemFromNum(4);

If your data is on the first worksheet, use '1' instead of '4':

worksheet = worksheets.itemFromNum(1);
