Json To Vcf Converter Review

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | JSON is an object {} not array [] | Wrap your object in square brackets: [...] | | Phone numbers missing | JSON key is "mobile", not "phone" | Edit the JSON to use "phone" OR use a converter that allows custom key mapping. | | Names appear as "Undefined" | JSON key is "fullName", not "name" | Pre-process JSON to rename keys. Use "Find and Replace" in Notepad++. | | Special characters (é, ñ) are garbage | Encoding mismatch | Ensure converter outputs UTF-8. If not, use a script. | | Only first contact imports | Missing END:VCARD or separators | Open VCF in text editor. Ensure each contact block ends with END:VCARD . | Part 8: Advanced Use Cases Converting Nested JSON Many APIs return nested JSON (address inside an object). A basic converter fails. Example:

[ "name": "John Doe", "phone": "+1-555-123-4567", "email": "john.doe@example.com", "company": "Acme Inc." ] APIs, databases, web storage. Weakness: Cannot be imported directly into a phone's address book. What is VCF (vCard)? VCF is a standard file format for electronic business cards. Each contact begins with BEGIN:VCARD and ends with END:VCARD . A standard VCF entry looks like this: json to vcf converter

Prepare your JSON. Ensure it is a valid array of objects: | Problem | Likely Cause | Solution |

import json import vobject with open('contacts.json', 'r') as f: data = json.load(f) Create VCF file vcf_file = open('output.vcf', 'w') | | Special characters (é, ñ) are garbage
