I think what people are trying to wrap there head around is how 800 lines in the file is being split into two subsets: the organization data and the people data. In particular how that is being done to preserve the relationship between organizations and people? This is before it ever gets to the database.
I agree. We keep going in circles and until we have a sample of the data, it's not a good use of time for us to keep guessing at what none of us is clear about but you - what the data actually looks like.
