Hi Annalise,
The only way you can apply Title Case (or Proper Case) to the
same column is with a macro. Take a look at http://www.mvps.org/dmcritchie/excel/proper.htm
also using a macro allows you to customize your results, because
not all words should have first letter actually capitalized.

Also use of a macro means you make a selection and invoke the
macro, you don't have to worry about extending a formula past
your data or not including all of your data in a column.
