# Emails for email in contact.get('email', []): lines.append(f"EMAIL:email")
Converting between JSON and VCF is a common task when migrating contact data between web applications (which often use JSON) and legacy or mobile systems (which rely on VCF). This guide covers both directions of conversion, including specifications, code examples, edge cases, and tooling. 2.1 The VCF (vCard) Format A simple vCard 4.0 example: vcf_output = [] for contact in contacts: vcf_output
# Structured name: N:last;first;middle;prefix;suffix n_parts = [ contact.get('lastName', ''), contact.get('firstName', ''), contact.get('middleName', ''), contact.get('prefix', ''), contact.get('suffix', '') ] lines.append(f"N:';'.join(n_parts)")
