Why Convert ICS to CSV?
ICS (iCalendar) is the universal calendar file format used by Google Calendar, Microsoft Outlook, Apple Calendar, and virtually all calendar applications. While ICS files are great for sharing events between calendar apps, they are difficult to read, edit, or analyze directly.
Converting ICS to CSV lets you:
- View events in a spreadsheet - Open in Excel, Google Sheets, or LibreOffice for easy reading
- Bulk edit events - Modify dates, times, locations, and descriptions across many events at once
- Analyze calendar data - Sort, filter, and create charts from your calendar data
- Migrate between services - Export from one calendar app and import to another
- Archive events - Keep a readable backup of your calendar history
