My events appear on the wrong day. What’s wrong?

This is almost always a date format issue. Check that your Start Date column uses a consistent format and that it matches one of the supported date formats.

Common pitfall: 03/04/2026 is ambiguous — it could be March 4 (MM/DD/YYYY) or April 3 (DD/MM/YYYY). iCal Studio attempts to detect the format automatically, but we strongly recommend using the ISO 8601 standard format YYYY-MM-DD to make this unambiguous.

Can I include multi-line descriptions?

Yes. Wrap the cell in double quotes and include line breaks within the quotes. Your raw file should look like the example below.

Subject,Description Team sync,"Agenda: 1. Status update 2. Blockers 3. Next steps" 

My CSV has extra blank rows. Is that OK?

Yes. Blank rows are skipped automatically.

The converter says my subject is missing. What should I check?

Make sure your CSV has a column named Subject (case-insensitive). If the entire row lacks a subject, that row is skipped with a warning rather than causing the whole conversion to fail.

How do I create recurring events?

The iCal converter does not currently support recurring events. Each row becomes a single, non-repeating event. For recurring events, you will need to create a separate row for each occurrence or configure recurrence rules directly in your calendar app after importing.

Why does it take forever for my subscribed iCal link to update?

Subscribing to your iCal feed via URL is a convenient way to keep your calendar synced, but it doesn’t happen instantly.

The conversion is failing or producing unexpected results

If your CSV conversion isn’t working as expected:

1. Verify your CSV format matches our supported format
2. Check that required columns (Subject, Start Date) are present
3. Test with a smaller sample first (just a few rows)
4. Review any error messages provided by the converter

If you need help, please contact us at hello@ical.studio and include a sample of your CSV file (or the full file if it doesn’t contain sensitive data). This helps us debug the issue quickly.

Which calendar apps support iCal import?

Most calendar applications support iCal (.ics) files:

• Google Calendar – import via CSV or upload .ics file
• Outlook – import .ics file directly
• Apple Calendar – import .ics file from Finder or Mail
• Yahoo Calendar – import through settings
• CalDAV-compatible calendars – subscribe to .ics feed URLs

Is my data safe when converting CSV?

Yes. All processing happens in your browser. iCal Studio does not send your CSV data to any servers or store it anywhere. Your data stays completely private and local to your device.
