Hi Keerthi,
I have tried that. But the thing is, say if the cell is of type date, in excel there're lot date formats like "m/d/yyyy", "[$-F800]dddd,mmmm dd,yyyy", "d-mmm" etc.. we can't check for each and every format and verify whether it is a valid date or not. So instead of NumberFormat property, don't we have any other property or method which can return a generic data type instead of a formatted string.
Thanks,
Nivas.
