Define a text field to receive the full name text. Define auto-enter calculations on the first and last name fields that extract the first or last name. Enable auto-enter options during import (Careful this enables ALL auto enter options--not just these two calculations and the names will be automatically parsed into the first and last name fields.)
You can also just import the full names into the text fields and use Replace Field Contents with the same calculations to parse the name field.
The trick here is in creating calculations that work with also possible name combinations. You don't indicate in your example if this is possible, but you often find middle initials, two word first names, hyphenated last names, Jr. Sr. III and other text in your full name field and your calculations have to correctly handle all the different possibilities.
LeftWords ( FullNameField ; 1 )
Would return the first word as the first name.
RightWords ( FullNamefield ; WordCount ( FullNameField ) - 1 )
Would return all other words into the last name field, but that still leaves the issue of whether any middle initials etc. might exist in your data and into what field you would like to parse that data.
Thanks so much.
I was able to get the answer done nicely.
