Importer for Calendar is a Mac application designed to convert spreadsheet data into calendar events. Users can directly add the events to Apple Calendar or save them as .ics files for import into other calendar applications. The app supports recurring events including custom recurrence rules, attendees, and alarms, and guarantees full privacy through local data conversion that takes place entirely on your Mac.

Features

Any table structure

Import from any spreadsheet layout without hassle — no rigid file formats required. Just paste your data from Numbers, Excel, or CSV.

Recurring events

Full support for recurring events including custom recurrence rules — import weekly meetings, monthly reminders, and more.

Duration support

Effortlessly import events with specified durations, not just defined end times — ideal for time tracking and scheduling.

Export as .ics file

Save converted events as .ics files for use with Fantastical, BusyCal, Outlook, Google Calendar, or any other calendar app.

Time zone support

Handle diverse date, time, and time zone formats with ease — including different time zones for start and end dates.

100% private

Importer for Calendar doesn't collect any data — all conversion takes place locally on your Mac, a clear advantage over online converters.
