Well,
You can try a automation solution: Copy the strin into clipboard then paste it in a new excel sheet.
try this:
_cliptext=MyMemoField
oExcel = CreateObject("Excel.Application")
oExcel.Visible = -1 && for debugging
oexcel.WindowState = -4140
oExcel.Workbooks.Add()
oSheet = oExcel.ActiveSheet
lcCell = 'A1:B2'
oSheet.Paste( oSheet.Range( lccell ) )
oexcel.WindowState = -4137
Lccell is the range of cells where You want to paste. If there is going to be a messagebox telling U that the range does not corespond with the clipboard or something like that please corect lcCell.
Good luck,
