What is ICS?
ICS is the iCalendar format used to share calendar events between Google Calendar, Apple Calendar, Outlook and other planners. An .ics file holds one or many events as plain text.
Common uses for ICS
- Reviewing a calendar export in Excel
- Creating many events at once from a spreadsheet
- Archiving appointments in a readable table
Note: Recurring-event rules are listed as text rather than expanded into single dates, and attendee lists and reminders are not included in the table.
Compatibility: Supported by Google Calendar, Apple Calendar, Outlook, Thunderbird and most calendar apps.
