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. json vcf 変換

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:
