How it works.

  1. 01Open an ICS file.
  2. 02Choose master rows with RRULE preserved or finite occurrence expansion.
  3. 03Inspect the tabular preview and download formula-safe CSV.

The important details.

CSV is intentionally lossy for alarms, attendees, custom properties and nested components. The warning is explicit; retain your source ICS.

A good question.

Are spreadsheet formulas safe?

Potential formula prefixes are escaped in exported text cells. Never disable spreadsheet protections for untrusted files.

Keep going.
