automate formating a mailing list

Is there a way or macro or Excel add-on that would automate the
formatting/editing of a large raw data mailing list ?
I regularly get an Excel file with a column formatted as follows...which I
have been using 'text to column' routines to format...but it is very time
consuming. Here's a sample of the cells various configurations:

Judy Sample
Judy & John Sample
Judy E & John Sample
Judy E & John R Sample
Camelback Properties LLC
Desert Condominiums Co Inc

I have been using 'text to column' with the 'space parameter...but as you
see get about 4-5 columns which I then have to try to fit together as
follows:

FirstName (Column A) LastName (Column B)

Judy Sample
Judy & John Sample
Camelback Properties LLC

and so on..get anywhere from 500 to 4000 new names per month....!!...any
ideas on how to automate this task other than 'text to column' ?

Thanks, Tim
