Hi, im retrieving the data from a aspx page. The data is a X

Hm… I’m not sure about purpose of such initialization, Even if you will provide formula as part of cell ( it not possible for now, but just in threory ) it will immideatly override the value in column with calculated one - you will not be able to use it. Or do you see some other usecase ? ( while it not possible in common case, it may have some workaround for specific situation )
