Frequently Asked Questions

iCal (ICS) is a standard format for calendar data defined by RFC 5545. It's used by Google Calendar, Apple Calendar, Outlook, and most calendar applications worldwide.

No. All processing happens locally in your browser. Your calendar data never leaves your device. Perfect for personal calendars and business meeting schedules.

Each event becomes a JSON object with fields like uid, title, start, end, allDay, location, description, organizer (object with email/name), status, created, lastModified, recurrence (object), and attendees (array).

Dates are converted to ISO 8601 format (YYYY-MM-DDTHH:mm:ss for timed events, YYYY-MM-DD for all-day events). UTC times use the Z suffix.

Recurrence rules are parsed into a structured object with fields like frequency (daily, weekly, monthly), interval, count, until, byDay, byMonth, and byMonthDay.

Yes. Enable 'Include attendees' to add an attendees array with each attendee's email, name, and participation status (accepted, declined, tentative, needs-action).

Organizers are structured objects with both email and name (CN) fields. For example: organizer: {email: 'alice@example.com', name: 'Alice Smith'}.

Absolutely. Convert iCal data to JSON for REST APIs, JavaScript calendar libraries, or integration with modern web applications that work with JSON.

Multi-day events have distinct start and end dates/times. The allDay boolean field indicates whether it's a timed event or all-day event.

Uncheck 'Include empty fields' to create compact JSON with only populated fields. This reduces file size and makes the data cleaner for API consumption.
