I couldn’t find a decent way online to convert ICS files into an Excel type format for easy manipulation, or adding to documents etc.  So I’ve built a simple one that is now available online:

http://csv2sql.evandavey.com/ical2csv.php

This takes an iCal URL and provides you with a CSV file as a download.  Makes it much easier to get a list of dates from ICS files and use them for other purposes.

Also available is the CSV2SQL converter that I made last year, taking CSV files and coverting them into INSERT/UPDATE statements for use on a database.
