Combine the JSON arrays into a single array first (using a text editor or jq ), then convert. Python makes this trivial: all_contacts = json1 + json2 .
The conversion from JSON to VCF is a process of mapping and serialization. It is the transformation of a flexible schema into a rigid, standardized one.
Mapping was the fun part. The VCF format had its own language—N: for name components, TEL;TYPE= for phones, EMAIL for emails, ADR;TYPE= for addresses. She wrote mapping rules that handled multiple numbers, with labels converted to VCF types (work, home, mobile). For notes and company fields that had no exact VCF counterpart, she tucked them into the NOTE property.

Great for one-off tasks. You upload the file, and the site spits out a .vcf . Note: Be cautious with sensitive data on free public sites.

Method 2: The Desktop Software Approach (Secure & Bulk Processing) json to vcf converter
In today’s digital world, contact management is the backbone of personal and professional communication. Whether you’re a developer handling large datasets, a marketer managing lead lists, or an everyday user switching phones, you’ve likely encountered two popular data formats: (JavaScript Object Notation) and VCF (vCard, also known as .vcf files). But what happens when you need to turn structured JSON data into a universally importable contact file? You need a reliable JSON to VCF converter .

Before you upload your JSON file to a random website, consider this: Combine the JSON arrays into a single array
If you are looking for specific, free online converters, FileConverts is a common choice for various text format conversions. For developers, writing a Python script often provides the most control over the final mapping.
Depending on your technical comfort, you can choose from several approaches:
