This article describes the two formats that use the VCF file extension. It also explains how to open both formats and how to convert them from VCF to CSV.

A file with the VCF file extension is a vCard file used for storing contact information. In addition to an optional binary image, it is plain text and can contain details such as the contact's name, email address, physical address, phone number, and other identifiable details.

Because they store contact information, these files are often seen as the export/import format of some address book programs. This makes it easy to share one or more contacts, use the same contacts in different email programs or services, or back up your address book to a file.

VCF also stands for Variant Call Format and is used as a plain text file format to store variations in gene sequences.
