Sorry for the trouble importing your contacts! Did you see any sort of error message? When you tried to import your contacts, did you get a security email in your iCloud account or on your iPhone, iPad, or computer?
I have the same issue with icloud contacts & Google. My login ID for iCloud is my email address (email@example.com). When I try to import into Google, I get error message saying that is a Google account, please enter the correct iCloud ID….Stuck in a loop just go round and round and can’t see any way around it. (I did generate an app-specific pw in Apple, but I can’t even get to the place where I can enter it!) Any help will be appreciated.
You’re seeing the error because Gmail is only able to import information from iCloud email accounts.
However, you can still transfer your contacts using a backup file. First, use these instructions to save your iCloud contacts as a vCard file: https://support.apple.com/kb/PH3606
Then you can import the vCard file into your Gmail account:
1. Go to the old version of Google Contacts.
2. Click More and then Import.
3. Click Choose File.
4. Select your vCard file.
5. Click Import.
