I found out the other day that the carriage return can be used as a delimiter when converting text to columns. This is useful if you have in-cell carriage returns that you want to get rid of. (To do an in-cell carriage return in the first place, you just hit Alt+Enter.)
Highlight your column of data, making sure the columns to its right are empty. On the Data ribbon, hit Text to Columns. Hit the Delimited option, and then check the Other option. Click in the box where you are to type the delimiter and press CTRL+J.
Hey presto, text to columns!
