How to open an ICS file in Numbers for calendar audit?

Hi there. I am trying to do a calendar audit with GCal. I exported and downloaded the ICS file. How do I open it in Numbers to analyze? We do not/cannot use Excel at work.


Many thanks!

At its heart, .ics files are little more than structured text..


To answer your question literally, you can just rename the .ics file to .txt and Numbers will happily open it.


What it won't do, though, is interpret the data other than 'each line goes into its own cell'. If your goal is to get the data into some structured format so you can analyze the data you'll have some cleanup work needed to extract the relevant data. That may be well within your means, or it may be a stretch...


The other approach is to write a script that reads the .ics file, extracts the data you want and populates the spreadsheet. This may or may not be easier than opening the .ics in Numbers and extracting the data there.

If you will have to do a lot of this then you could consider importing the .ics to the built-in Calendar app and then using Export Calendars Pro (available on the Mac App Store) or similar to export to csv, which Numbers can then open.


A Shortcut or standalone script to pass data from Calendar to Numbers is also possible. It would be easier than having a script parse an .ics file directly, but would still entail a lot of work to set up and get working properly.
