Using the reccomended method of recording a VBA macro, I found that the following two lines
put the text to the top and left of the cell.

$sheet -> Range("B2:J2") -> {HorizontalAlignment} = xlHAlignLeft;
$sheet -> Range("B2:J2") -> {VerticalAlignment} = xlTop

It still would be good to know how to make the height of the row to fit exaclty the height of however many lines of text there are.
