Keep each event on its own row and include clear date/time values. Example headers: Title, Start, End, Description, Location. If your headers differ, the mapping step lets you match them manually.

In Google Calendar, use Settings then Import and select your .ics file. In Outlook, choose Open & Export, then Import/Export and select iCalendar (.ics). Review timezone and duplicates before final confirmation.
Is my event data private?
Yes. This tool uses zero-upload client-side processing, meaning your event spreadsheet remains on your machine throughout parsing, mapping, and ICS generation.
Frequently Asked Questions
What date format should I use in the CSV?
Use consistent date formats like ISO (YYYY-MM-DD HH:mm) for best results. The converter attempts to parse most standard date/time strings.
Can I leave description or location empty?
You should map all required fields in this tool flow, but empty values in rows are still allowed and simply produce blank ICS fields.
Does this support bulk event migration?
Yes. The converter is built for bulk import scenarios and generates VEVENT blocks for each valid CSV row.
