Import ICS to Apple Calendar

Need to get an .ics file into Apple Calendar on your Mac? You can open a ready-made ICS directly in Calendar – and when you only have a spreadsheet, Importer for Calendar turns it into a clean ICS (or imports the events straight away). No subscription, everything stays on your Mac.

How to import an ICS file into Apple Calendar

  1. Double-click the .ics file – Apple Calendar opens and offers to add the events.
  2. Choose the target calendar and confirm the import.
  3. No ICS yet? Open Importer for Calendar, load your CSV/Excel data and export a valid .ics file.
  4. Import that ICS into Apple Calendar, or let the app add the events directly.

Open an ICS file on Mac

Apple Calendar can open an .ics file directly, but malformed or multi-event files often fail. Importer for Calendar builds a clean, standards-compliant ICS so opening the ICS file on Mac just works.

ICS to iCal – events that arrive complete

Dates, times, time zones, durations, recurring events, alarms and attendees are all preserved, so converting ICS to iCal keeps every detail instead of bare titles.

Add ICS to calendar from any spreadsheet

Have your schedule in CSV or Excel instead of ICS? Importer for Calendar maps your columns and produces the ICS for you, ready to add to the calendar.
