[Jprogramming] J OLE server for Excel

[Damien]

Hello,

I am currently using J as server for Excel with OLE. I would like to deal
with the problem of empty cells or wrong type of value (string) with J, and
not with Excel.
The problem is that I can not send any "wrong" data to J. When the data are
correct, J receives them as boxed array. As boxed arrays rare very
convenient to deal with different type of data, I am a little surprised.
Do you know if it is possible to do what I want ?

Thanks.
Damien.
