Very cool, thanks for letting me know @tkarpinski

Yeah the comments import in Jira is a bitch. As you can see from the script you need a column for every comment and you have to format them in a special way so that the comment user and date is picked up (WTF?).

This code was very helpful to me in understanding what data to produce for JIRA. But it didn't handle enough of the data for what I needed, I ended up writing a somewhat more complex exporter (in Clojure). In addition to comments, I bring along events (open/closed), maps usernames, and carries over milestones and labels.
