I am managing my appointments using Outlook on windows and iCal on OS X. Since I am not using any Exchange service right now I was happy to find out that Outlook offers a functionality to export a local calendar automatically to an iCalendar compatible ICS file. Great feature but it lacks some things I desperately need.
Since I am managing my private and my business appointments in the same calendar, differentiating just by categories, I had a hard time configuring outlook to export a) an ics file containing all business appointments and b) an ics file containing all private appointments. It’s not possible to make the story short.
So I fired up Visual Studio as usual and wrote my own filter tool. I shall call it “iCalFilter”. It’s name is as simple as it’s functionality and code. I am releasing it under BSD license including the sources so everyone can use and modify it.
It’s a command line tool which should compile on Microsoft .NET and Mono. It takes several command line parameters like:
- “include” or “exclude” –> this determines if the following categories are included or excluded in the output file
- a list of categories separated by spaces
- an optional parameter “-remove-description” which, if entered, removes all descriptions from events and alarms

UPDATE: You can now access the source code on github! You can even add your changes!
One thought on “small tool to filter iCal / iCalendar / ICS files”
Super, vielen Dank! Ich musste meinen in Kategorien eingeteilten Kalender aus Thunderbird für Google in einzelne Kalender aufteilen. Wollte schon ein PHP-Script dafür schreiben, dann habe ich Dein Tool gefunden. Funktionierte auf Anhieb.
