Thanks so much for crafting and sharing this, lot3oo. I've been archiving Calendar.app events via icalBuddy[1,2] like so[3], but there's no telling how much longer it will work (last update was a decade ago). Having a straightforward shell script that can convert ICS to CSV should work well for a long time to come (so long as Apple doesn't pull support for exporting to ICS, of course). Thanks again!
