How it works
Turn a calendar file into a reviewable CSV
02
Choose recurrence handling
Keep source events as they are, or expand supported repeating events into separate CSV rows.
03
Review and download
See source records that need review before exporting readable events with their original clock times.
Example
Keep a 9:00 meeting at 9:00
If an ICS file contains DTSTART:20260617T090000, the CSV keeps the event's start time as 09:00. When you expand a supported repeating rule, each occurrence keeps that same local clock time instead of being shifted to another hour.
Questions
ICS to CSV details
Will event times change?
No. A floating event time such as 09:00 stays 09:00 in the CSV. Timezone, all-day, and recurrence details are exported separately instead of silently converting the event time.
Can repeating events become separate rows?
Yes. Turn on recurrence expansion to create a row for each supported daily, weekly, monthly, or yearly occurrence. The original RRULE is kept in every row so the source rule remains visible.
What happens when an event is incomplete or uses a complex recurrence?
A malformed VEVENT, EXDATE exception, or unsupported recurrence is reported with its UID when available and stays as one source event. Other readable events can still be downloaded.
