I have a cell that looks like this

John Doe 123 N. 1st Street Miami, FL 12345

Is there a formula, or something I can do to get it to look like this

John Doe
123 N. 1st Street
Miami, FL 12345

Without having to go through and press enter and resize all of the column
widths. I swear I've seen something that looks like a little box that you
can put between things in a cell that will make it automatically drop to the
next line.

Thanks!!
