It is possible to include or not genotype information on samples for each position. If there is genotype data in the file, it is followed by a FORMAT column header and then any number of sample IDs. The header is delimited by tabs. The header starts the file and provides metadata that describes the body of the file. Headers are labeled to start with #. Special keywords in the header are marked with ##. Recommended keywords include fileformat, fileDate, and reference. If a VCF file contains an image, that part of the file is binary and does not appear in a text editor. However, other information must be fully visible and editable in any program that works with text documents. Microsoft Outlook supports opening VCF files as well as converting to a number of other formats such as the popular MSG format. The VCF file format has been extended over time from version 2.1 to 4.0 and detailed information has been added to the file format. The format is also used to export phone contacts and later to import them to another device.

What are the alleles in the above cases and how would they be represented as a VCF dataset? VFC (VentaFax Cover Page), FCF (Final Draft Converter) and VCD (Virtual CD) are just a few examples. If you really have one of these files or something else, do some research to learn more about the format and program you need to open. VCF files can also be imported into online email clients such as Gmail. On the Google Contacts page, find the Import button and select the VCF file in the Select File button. Windows People is integrated with Windows 10 (Contacts in Windows Vista and later versions of Windows) and can be used to open VCF files, as well as vCardOrganizer and VCF Viewer. On a Mac, VCF files can be viewed using vCard Explorer or the Address Book. The VCF file extension tells your device which application can open the file. However, different applications can use the same file extension for different types of data. Therefore, a VCF opener may not be able to open all kinds of VCF files. In this case, look at both formats to make sure you find the most suitable VCF viewer. VCF files are tab-delimited text files. Here is an example of a variant in VCF (Figure 12) as it appears in a spreadsheet: Because VCF files are plain text files, you can open and examine them using any text editor such as Microsoft Notepad (Windows), Apple TextEdit (Mac), or GitHub Atom (cross-platform).

In Excel, navigate to File > Open and select All Files. Locate and select your file. Then follow the Import Text Wizard and your .vcf file will appear in Excel. The Handy Address Book program mentioned above is one of the best offline VCF to CSV converters. Use the File > Import menu to open the .vcf file and view all contacts. Then select the one you want to export and navigate to File > Export to select the output type (it supports CSV, TXT and ABK). Since VCF files store contact information, they are often considered 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 save your address book to a file.

You can open VCF files with various applications. Windows users can open vCards with Windows Contacts and Microsoft People (included with Windows) and Microsoft Outlook (an email client included with Microsoft Office). Mac users can open vCards using the Contacts app that came with macOS. Android and iOS users can also load vCards directly into the Contacts apps that come with their respective operating systems. File metadata is inserted after the string ##, often as key=value pairs. VCF is a preferred format because it is unique, scalable and flexible so that additional information can be added to the information box. Several million variants can be stored in a single VCF file. The body of VCF follows the header and is divided into 8 mandatory columns on the tab and an unlimited number of optional columns that can be used to save other sample information. If additional columns are used, the optional first column is used to describe the format of the data in subsequent columns. The Variant Call Format (VCF) specifies the format of a text file used in bioinformatics to store variations in gene sequences. The format was developed with the advent of large-scale DNA genotyping and sequencing projects such as the 1000 Genomes project.

Existing formats for genetic data, such as the General Characteristics Format (GFF), stored all genetic data, many of which are redundant because they are shared between genomes. Using the variant call format, only variations should be recorded with a reference genome.
