Importer for Calendar: CSV,ICS

Importer for Calendar lets you convert spreadsheet data into calendar events. You can import the events directly to Apple Calendar or save them as .ics files to import them to another calendar app.

As an easy to use CSV to Calendar events converter, Importer for Calendar comes with many thoughtful features. Simply copy your data in your spreadsheet app to the clipboard and then paste it into Importer for Calendar to convert it into calendar events. You can save field assignments for recurring imports, so you don't have to do the assignment from scratch each time. You can preview the conversion result before importing, using a list view or a detailed individual preview per event. To work with third-party calendars like Fantastical or BusyCal, you can save the converted events as .ics file.
The app can handle a variety of date, time and duration formats and also supports the creation of alarms.

The following features set the app apart from alternatives:

- Supports the import of events with a specified duration instead of a defined end time.
- Supports a wide range of date and time formats.
- Supports conversion to .ics files
- Supports recurring events, including exotic custom-defined rules and auto-detection.
- Supports Outlook categories and BusyCal tags when exporting as .ics file
- Allows flexible import from any table structure. There is no need to provide an import file in a predefined rigid structure.
- Privacy: Conversion and import of your data takes place completely locally on your Mac.
- Genuine, modern Mac app, not an iOS application ported to the Mac.
