What becomes a CSV row?

Each VEVENT becomes one CSV row with Title, Start, End, Location, Description, Categories, Recurrence, and UID columns.

Does ICS to CSV expand recurring events?

No. Recurrence rules are carried as text when present and should be reviewed rather than treated as expanded occurrences.

Will every ICS property appear in CSV?

No. Attendees, reminders, alarms, time-zone definitions, exceptions, conferencing links, and custom properties are outside the basic conversion schema.

What this workflow does

ICS files contain calendar components and VEVENT properties. CalendarFlow reads common event values and writes one CSV row per VEVENT. The output columns are Title, Start, End, Location, Description, Categories, Recurrence, and UID.

ICS: SUMMARY:Project review · DTSTART:20260715T160000Z · DTEND:20260715T170000Z CSV: Project review, 20260715T160000Z, 20260715T170000Z

That structure is useful for reviewing event lists in a spreadsheet, but a CSV row cannot express every property from a rich calendar file.

How to export ICS events to CSV

Open the working converter and choose an .ics or .ical file.
Review the event count and the visible title, start, end, and location preview.
Check any notice about recurrence rules and inspect dates before export.
Leave the output format set to CSV, then download the generated spreadsheet.

Time and recurrence checks

A timestamp ending in Z represents UTC. Date-only values can represent all-day events, while named time zones and daylight-saving changes need a destination-side review. CalendarFlow carries recurrence text but does not expand rules or apply exception dates.

Limitations to expect

Attendees, organizers, reminders, alarms, conferencing links, attachments, and custom properties are not included in the basic CSV schema.
Named VTIMEZONE definitions are not reconstructed as spreadsheet columns.
One VEVENT becomes one row; a recurring event is not turned into a row for every occurrence.
Use the comma-separated CSV output as a review/editing format, not as a guarantee of provider-perfect round trips.

ICS to CSV questions

Can I open the CSV in a spreadsheet app?

Yes. The output is a standard comma-separated file with a header row, so it can be reviewed in spreadsheet software. Check date interpretation before saving changes.

Why are some calendar details missing?

The basic schema focuses on common VEVENT fields. Properties such as attendees, reminders, alarms, conferencing links, and provider-specific extensions are not mapped.

Is my ICS uploaded?

No. The converter reads the file locally in your browser.
