Hi Alan,
One additional word of warning on this. If the first column that has data is NOT the first column in the sheet then that code won't work exactly right. For example, if column 1 is empty, and columns 2 - 10 have data, then num_cols would return 9, and this_row would be "a1:i1" when what you really wanted was "b1:j1".
Using o.Application.ActiveSheet.UsedRange.Column will return the value of the first USED column in your excel sheet. Therefore your 'this_row' variable would become:

begin_col= o.Application.ActiveSheet.UsedRange.Column
this_row = chr( 97 + begin_col - 1 ) + "1:" + chr( 97 + begin_col - 1 + num_cols - 1) + "1"

However, if you're sure your data will always begin in column 1, this point does not matter.

Happy Excelling.
