One row per VEVENT, including edited occurrences. Repeating series stay rules; this export does not silently flatten them into one-off events.

How to use this tool

Open or paste an ICS calendar.
Review events and the recurrence warnings.
Download a CSV with separate time-zone and recurrence columns.

Before you export

Are repeating events expanded?＋

No. A recurring master is one row, with its RRULE, RDATE and EXDATE. Modified instances appear in their own rows with a Recurrence ID.

Can this CSV be reimported without losing fields?＋

This is an inspection spreadsheet, not a lossless calendar backup. Keep the original ICS for attendees, alarms, custom properties and future reimport.

Uses the iCalendar standard. Keep the original file and test the output in your receiving calendar app.
