Beta: not all real-world formats are supported. Keep the original files and test conversion and import with a small set of events first.
Data to convert
Supports Docomo's legacy calendar format (vCalendar 1.0). Files stay in your browser and are not uploaded.
Convert multiple files together, up to 20 MB total. Extract ZIP files first.
Paste the entire file text (up to 20 MB in UTF-8). Contents are not saved or uploaded.
Time offsets and zones specified in the file take precedence. All-day event dates are unchanged.
Choose a file.
Conversion results
Not converted yet.
Review events
Showing the first 20 events. Check dates, times and recurrence after import.
Items to review
If an event cannot be converted, saving is disabled and the reason is shown. Notes, ToDos and app-specific settings cannot be imported as events.
Import into calendar
Google Calendar: on the desktop website, open Settings → Import & export and select the saved ICS file and destination calendar. File import is not supported in the mobile app.
iPhone / iPad: open the ICS as an email attachment, or import it into an iCloud calendar on a Mac and sync. Opening it in the Files app alone may not add it.
Import into a new calendar first and check the results. Repeated imports may create duplicates. This tool does not import or sync automatically.
