Show HN: Icsp – Command-line iCalendar (.ics) to CSV utility

[lot3oo]

Hey folks, I've written this pure bash ICS to CSV conversion tool after needing it for a personal use case.

It all started with realizing that the Google Calendar REST api was too much of a hassle to integrate for a one-off use case (need to change account settings, do a Oauth login & manage tokens...). I then remembered that calendar exports were just a few clicks away in the .ics format, so I decided to use that instead.

I couldn't find anything online other than half broken scripts or language-specific libraries to parse .ics files, so I then went ahead and wrote a straight forward, pure bash implementation for CLI usage.

Hope this is useful for others as well!

I put in a few examples to try out in the readme on Github, let me know if you try it out!

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!
