Bulk import events to Apple Calendar

Adding events one by one is slow. With Importer for Calendar for Mac you bulk import events to Apple Calendar from a CSV or Excel list – dozens or thousands at once. No subscription, all data stays on your Mac.

How to bulk import events into Apple Calendar

  1. Put your events in a spreadsheet – one row per event.
  2. Open Importer for Calendar and load the file.
  3. Map the columns to title, start, end, location and notes.
  4. Pick the calendar and import all events at once – or export them as an .ics file.

Add multiple events to your calendar in one go

No more copy-and-paste. Importer for Calendar adds multiple events to your calendar in a single pass, so a long list of dates is handled in seconds.

Mass add calendar events with full detail

Each row can carry start and end times, time zones, durations, recurrence, alarms and attendees, so mass-added calendar events arrive complete.

Batch add events on Mac – or export to iCal

Import many events into iCal directly, or save them as an .ics file to share – batch adding events on Mac scales from a handful to thousands.
