It can be much faster to import or export contacts instead of entering them one by one. However, not all apps that manage contacts use the same file formats. When importing or exporting contacts, you may want to check which formats are used by each app to make sure the app importing the contacts can read what the other app exported.
Open Windows Contacts by clicking the Start button , and then clicking your user name. Type contacts in the address bar, and then press Enter.
On the toolbar, click Import, and then click one of the following formats to import contacts from:
CSV (Comma Separated Values). This format is a generic and common file format, used by lots of apps, especially databases or spreadsheets. If you can't import an address book file directly into Contacts, try converting it first to a CSV file and then importing that file.
LDIF (LDAP server). This format is used to import directory information from LDAP-based directory servers.
vCard (VCF file). This is the most widely used contacts format.
Windows Address Book file (Outlook Express contacts). This format (.wab file) is used by most earlier versions of Windows, including Windows XP.
Click Import, locate the contacts file you want to import, and then click Open. The new contacts should appear in your Contacts folder.
If you can't find the contacts file you want to import, search online to learn more about the app that created the contacts and what file formats it exports. You might need to export contacts from the program before you can import them into Contacts.
When a message appears telling you that the contacts import process has completed, click OK, and then click Close.
When you export from Contacts, you can choose between two file types: .csv and .vcf.
On the toolbar, click Export, and then click one of the following formats:
CSV (Comma Separated Values). This format is a generic and common file format, used by lots of apps, especially databases or spreadsheets.
vCard (folder of .vcf files). This format is used by many other contact-management programs. It's typically the best format to use when sharing contacts with someone who is using an earlier version of Windows or a different operating system.
Click Export, select a folder where you want to store your contacts in the new format, and then click OK.
When a message appears telling you that your contacts have been exported in the new format, click OK, and then click Close.
