Predictable by design

iCalendar output follows RFC 5545’s CRLF exception, folds physical lines at 75 UTF-8 octets, escapes TEXT values, emits UTC timestamps with Z, and generates required UID and DTSTAMP properties. Calendar-only structures may flatten or be dropped when crossing to tabular data.

Frequently asked questions

How do I convert iCalendar to CSV?+

Paste or open iCalendar data, review any validation message, then copy or download the CSV result.

How are larger inputs handled?+

Inputs are capped at 20 MB. More expensive browser work reports progress, can be cancelled, and has a timeout so the page stays responsive.

Can information change during conversion?+

Yes. The formats model data differently, so some type or structural information may change. The converter documents its deterministic mapping on this page.

How are large integers and invalid values handled?+

Integers are retained as BigInt internally and become strings when JSON cannot represent them safely. NaN and Infinity produce a clear error instead of invalid JSON or rounded output.
