Bit of both. I have a WordPress (I know, shame on me) installation I customized for quick entry here: http://icopiedyou.com ) – and one day I exported it to XLS. Also made a backup copy of the same data on Gopher (protocol nobody uses anymore) just for fun.
One of these days I’ll refresh it with new data since the last time I made it. For that I guess I’d export the database to XLS again, updating the description and file.
