How it works.

  1. 01Choose a CSV file or paste quoted CSV text.
  2. 02Map title/date/time/end/location/notes columns and choose timezone.
  3. 03Review row errors and generated events, then export.

The important details.

Quoted commas, newlines and escaped quotes are parsed. Dates must use explicit ISO or a selected convention; invalid rows are not silently included.

A good question.

Do column names need to match?

No. Use column mapping. Recognized headers are suggested, but you confirm the mapping.

Keep going.
