Question : How do I "PROPER" Addresses on excel 2010?

I have a huge database that I would like to PROPER addresses, names and last names are easy, but addrsses are hard because they're not always one/two words.  How do I PROPER my DB with records like these:

354 S BASIL ST (I would like to make BASIL = Basil)
14181 YORBA ST  #200 ( I would like it to be "Yorba  St"
925 CATALINA ROSE (Iwould like it to be "Catalina Rose"

It doesn't matter how many words there are, the first letter of each word will be uppercased.
