I haven't used some of the cooler import features of Google Docs Spreadsheets, but my guess is that Refine will be better if
a) you are not skilled in a language that handles text easily (I have friends who might have a need to aggregate that data but would have no clue how to begin writing a program to parse it).
b) don't have a Peter Norving-like facility with algorithms: http://norvig.com/ngrams/ i.e. you could code the transformation given sufficient time, but Refine would be faster, both in development and, for large data sets, run time.
