First, in the .xls do a 'Find/Replace' of carriage returns with a pipe, i.e. for the 'find' value do Ctrl-J (which should give a blinking period) and replace with | (pipe).  Then in your import on the item desc field, use a Calc with something like this: SUB(Temp001$,"|",$0d$).  This basically takes the item desc in the VI temp field and replaces all pipes with a carriage return.

Beware of using the pipe "|" character like that.  It can really mess up the VI job.  Here are my notes on the technique.
