Why value is not coming in a particular cell in excel while downloading excel through OLE2 object?

Through OLE2_object when we are downloading an excel, in a particular cell (row:8:: col:27(AA)) 0.00 value is coming. But in backend there is data. If in run time I change the column then it is coming. Particularly in AA column this problem is coming. And the columns are dynamic.

Thanks & Regards,
