Tabular structure export

[ajinkya_c]

Hi,

I want export my report which is in tabular structure in excel but it give ERROR: Can't add cell & String can not be cast to number.

So I found the problem that I formate a field from table that if field ==null then replace it with NA or N/A text so when i removed that formatting then report get exported very well.

I required that formatting & excel export also.

Any help appreciated.

Thanks
