Put a list of valid states somewhere, in this case H1 - H50 then try this
formula:-


=IF(COUNTIF($H$1:$H$50,A1)0,"United States","")

drag down as required

Column A has states that are almost always populated, but B is often left
blank. I wanted to create some type of Array or Lookup that has all the
states in it, and them do a comparison; If what is in Column A is a valid
state, then populate B with "United States, otherwise leave it alone.

I can't use "IF" because there are too many arguments, and can't figure out
how to make it work with something like VLOOKUP.

Advice apreciated.
