Android Phones Contacts

If they're Google contacts then that can be done by logging into your gmail account on your pc & selecting contacts.

 

Export as vcf file to the PC, edit, delete phone contacts, import edited contacts to the phone.

 

If you are using a Samsung Phone, you can use Kies. If that doesn't work, you can use MyPhoneExplorer (works for other brands too).

I would personally suggest just putting the contacts up in Google.
