Cabrillo is an extremely easy to create ASCII (text) format.
Search the eHam Links for the word Cabrillo. The actual spec is referenced there, as well as at least one tool guy, WT4I.
Also, check the eHam Links categories of shareware and logging software - there might be a freebee in there somewhere.
I take it you used Excel to log the contest? I'm sure that's better than hand logging, but computer logging programs do a lot more for you than just the stuff you mentioned (which I guess you consider "fluff"). They write to hard disk each QSO, (I don't think you can get Excel to do that), dupe check automatically, maintain the multiplier check list - all important while you are operating. And there are "free" logging programs as well - search our links.
Anyway, good luck with the Cabrillo format.
