ICS to GCal Extension

*** NOTE: Google Calendar's own ICS import functionality has been improved and may replace ICS to GCal for you: https://calendar.google.com/calendar/r/settings/export ***

Found an interesting event online that comes as an iCal file (*.ics) and want to import it into one of your Google calendars? With ICS to GCal this will take just two clicks - no need to open the Google Calendar settings and pollute your list of calendars.

ICS to GCal correctly imports recurrent events (to the extent they are supported by Google Calendar) and automatically fixes some deviations from the iCalendar specification that are rather common (such as trailing commas in date lists, exceptional dates not specified with the correct time,...).

How to use:
0. Before the first use, click on the extension symbol in the browser toolbar to allow access to you calendars.
1. Right-click on a link to an iCal file (*.ics).
2. Select a calendar under \"Add to calendar\".
A popup notification will inform you about the number of events added and allow you to view the event or undo the changes while they have not been committed.

Sunil Kumar (ID: 0000005fbddc8bc4) Voted 4 ★ - Updated 11/07/2023 It did the job perfectly. Amazing. Some times i am getting a message that 'cant create events'. Any issues ?

Clinton Robertson (ID: 000000edf2e5463e) Voted 4 ★ - Updated 02/24/2023 The extension works great, but the instructions on how to use it are poor. I figured it out by experimentation. They are as follows: 1. add extension to Chrome. 1. Right click on an ICal file on a webpage and select the ICS to Gcal icon. 3. Select which Gcal to add it to. 4. Check it on your gcal.

Julia Tungli (ID: 00000097b763943e) Voted 5 ★ - Updated 03/23/2021 I have been using this for a very long time. It's one of my favorite extension. That said, I think something has changed. I frequently get an error now saying the ICS file is in the wrong format. I can still tediously go to my calendar and import it, so I feel like it should still work. Can you look into it? I don't even leave reviews normally, but I miss the smooth functionality...
