QUICK ANSWER
Is it possible to convert VCF to VCS?
No - not a direct conversion.

There is no VCF-to-VCS conversion - a contact card has no event dates, and a calendar event has no name or phone fields. If you want to add someone's birthday to your calendar, create the event manually in your calendar app.

No direct path

Why convert VCF to VCS?

A .vcf (vCard, RFC 6350) holds contact records - name, phone, email, address. A .vcs (vCalendar) holds scheduled events and to-do items with dates and times. These two formats live in separate domains and have no shared data model, so a conversion produces either an empty file or a broken one.

How to convert VCF to VCS

Microsoft Outlook (import contacts) APP

Import the .vcf directly into Outlook contacts via File > Open & Export > Import/Export > Import a vCard file to use the contact data as intended.

Apple Calendar (open VCS directly) APP

If your goal is to access .vcs calendar data, open it in Apple Calendar via File > Import - no conversion needed; Apple Calendar accepts .vcs files directly.

Quality & what to watch

  • VCF (vCard) and VCS (vCalendar) were both developed by the Versit Consortium in the mid-1990s, causing name confusion, but they store contact data and calendar data respectively - they were always separate standards.
  • VCS has been largely superseded by ICS (iCalendar); most calendar apps (Outlook, Google Calendar, Apple Calendar) accept .vcs files directly.
  • To add a birthday from a contact to your calendar, open the contact in your contacts app and create the calendar event manually - no file conversion is involved.

Frequently asked questions

Why do some websites offer VCF-to-VCS conversion?
They pair file extensions without checking whether the output is meaningful; the result is an empty or broken file because the formats have no shared fields.
Is VCS related to VCF?
The names look similar and both are plain-text line-based formats from the mid-1990s Versit Consortium, but vCard handles contacts and vCalendar handles calendar data - they were always separate standards.
How do I get contact data into a spreadsheet?
Convert .vcf to CSV instead: import into Google Contacts at contacts.google.com and export as CSV.
Can I open a .vcs file without converting it?
Yes - Google Calendar, Outlook, and Apple Calendar all accept .vcs files directly via their import functions.
