Did you ever lost your contact list from your iPhone? Do you ever wish to back up your iPhone contacts to a single file? You can save your iPhone contacts into a single file and save anywhere you want. Even you can send your iPhone contact file by email. It is good to keep an additional backup of your contacts once in a month just for the peace of mind.
If something happen to your iPhone contacts, you can easily recover all data from this file simply by importing those. You need only iCloud account and iPhone to follow these procedure. If you don’t have a iCloud account, please refer this post to get a free Apple ID (iCloud account) which can be used to backup your iPhone data.
Make sure you configured iCloud account in your iPhone. Go to your iPhone,
Settings > iCloud > Make sure you turned on the Contacts sync with iCloud like the screen shot.
You are done with the iPhone setting. Next go to www.icloud.com. Log in with your credentials. Select on Contact icon, make sure you have the same number of contacts in your iPhone and iCloud account.
Once you open the Contacts window, click on the lower left settings icon, and click on ‘Select All’ to select all the contacts from your list. Please click on Export vCard to export your entire contact list as a vcf format to a single file.
The next pop window will ask you to confirm the file name and the location to save file. Save the file with required file name and vcf extension. You can keep this file to recover your contact list in future or you can send the contact list to anybody by email and they can use the contact list to import to their own list.
Please see this post here to see how to transfer iCloud contacts to Google Contacts. You can use this file to import contact list to your Android phone too.
