Not elegant, but a suggestion might be to export half the data to one cell, the other half to another, contatinate (=A1&A2) in to target cell and then delete the data in the temporary cells.

Or perhaps, you could export the data as two strings (cell.value = string1 & string2).

To be honest, don't really know but this is what popped in to my mind as possible things to try.
