# Handle both array and object-with-contacts-array formats if isinstance(contacts, dict) and 'contacts' in contacts: contacts = contacts['contacts']

Its human-readable structure uses key-value pairs and ordered lists, making it ideal for transmitting data between servers and web applications. Tap the file and select "Add all contacts
Online converters may time out. Use a script or a desktop application (e.g., CSV to VCF converters can also handle JSON with a pivot). For massive conversions, consider splitting the JSON into chunks of 500 contacts.
import json import vobject # Sample JSON data json_data = ''' [ "firstName": "John", "lastName": "Doe", "email": "john@example.com", "phone": "123-456-7890" ] ''' contacts = json.loads(json_data) for contact in contacts: j = vobject.vCard() j.add('n') j.n.value = vobject.vcard.Name(family=contact['lastName'], given=contact['firstName']) j.add('fn') j.fn.value = f"contact['firstName'] contact['lastName']" j.add('email') j.email.value = contact['email'] j.email.type_param = 'INTERNET' j.add('tel') j.tel.value = contact['phone'] j.tel.type_param = 'CELL' # Save the VCF with open(f"contact['firstName'].vcf", "w") as f: f.write(j.serialize()) Use code with caution. 3.
