Json Vcf 変換 May 2026

1. Introduction The vCard (VCF) format is a long-standing standard (RFC 6350) for electronic business cards, widely used in email clients, mobile phones, and contact management systems. JSON (JavaScript Object Notation), on the other hand, is a modern, lightweight data-interchange format favored by web APIs and databases.

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: json vcf 変換

# Full name lines.append(f"FN:contact.get('fullName', '')") widely used in email clients

# Organization if 'organization' in contact: lines.append(f"ORG:contact['organization']") on the other hand
