Excel mailing list in wrong format for mail merge
 

I have been handed a list that I need to convert and I am stumped.

The worksheet contains three columns of addresses. The addresses are
generally in one of three formats:

Company
Contact
Street number and name
City State
Zip

or

Name
Street number and name
City State
Zip

or

The repeat of the above with two lines for street information.

As far as I can tell so far, these four are the only the different
formats.

Some of the addresses have a comma between the city and state.

One final complication, some addresses use the 5 digit zip, some use
the zip+4 with a dash.

Is there a way to convert these columns into approptiate rows so this
can be used as a mail merge?
