You can import JSON into a spreadsheet, organize the columns to match vCard standards, and then use a "CSV to VCF" tool. This is a great middle-ground for those comfortable with Excel but not with coding. Key Data Mapping Tips
import json
This works but lacks escaping for special characters – use only for trusted data.
import json def json_to_vcf ( json_file , vcf_file ): with open(json_file, ' r ' ) as f : contacts = json.load(f) with open(vcf_file, ' w ' ) as f : for contact in contacts: f.write( " BEGIN:VCARD\n " ) f.write( " VERSION:3.0\n " ) f.write( f " FN: contact.get( ' name ' , ' ' ) \n " ) f.write( f " TEL;TYPE=CELL: contact.get( ' phone ' , ' ' ) \n " ) f.write( f " EMAIL: contact.get( ' email ' , ' ' ) \n " ) f.write( " END:VCARD\n " ) # Usage json_to_vcf( ' contacts.json ' , ' contacts.vcf ' ) Use code with caution.

✅ Save VCF as UTF-8 with BOM or use CHARSET=UTF-8 in the file.
JSON is a lightweight, text-based data format. It uses key-value pairs and arrays to store data in a way that is easy for humans to read and easy for machines to parse.
The JSON file uses UTF-8 characters (like accents or symbols) but the VCF interpreter reads it in ANSI format.
There are vCard versions 2.1, 3.0, and 4.0.
