Why Convert ICS to CSV?

Converting ICS to CSV is a common task whenever a file has to work somewhere that expects the other format. ICS is the iCalendar format used to share calendar events between Google Calendar, Apple Calendar, Outlook and other planners. CSV is a plain-text format for tabular data where each line represents a row and commas separate column values. This converter makes the switch locally in your browser — nothing is uploaded.

Common use cases

  • You have a ICS file and need it in CSV format.
  • The target software or platform requires CSV but your file is in ICS.
  • Typical use of CSV: Exporting database records for analysis in Excel or Google Sheets.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: CSV has no standard for data types, number formats, or multiple sheets — all values are stored as text. Commas inside values require careful quoting.

How to Convert ICS to CSV
