2. LambdaTest JSON to VCF

  • Best for: Developers testing API outputs.
  • Features: Syntax highlighter, error checker.
  • Limitation: 50,000 character limit.

Pros: Instant, free, no setup. Cons: Privacy concerns (sensitive contact data is sent to a server), file size limits (usually <5MB). The Ultimate Guide to JSON to VCF Conversion:

1. Load your JSON file

with open('contacts.json', 'r', encoding='utf-8') as f: contacts = json.load(f) Best for: Developers testing API outputs

  • Escape special characters – Commas, semicolons, and newlines need proper escaping in VCF.
  • Batch size – For 500+ contacts, split into multiple VCF files (some phones choke on large files).

    • 4. Mapping JSON Fields to VCF Properties

    | JSON Field | VCF Property | Notes | |------------|--------------|-------| | fullName | FN | Required | | firstName + lastName | N | Structured: N:last;first;middle;prefix;suffix | | nickname | NICKNAME | | | phoneNumbers[].number | TEL | Add TYPE parameter | | emails[].address | EMAIL | Add TYPE parameter | | addresses | ADR | Structured: ADR;TYPE=home:;;street;city;state;postal;country | | organization | ORG | | | jobTitle | TITLE | | | birthday | BDAY | Format: YYYY-MM-DD | | notes | NOTE | | | website | URL | |

    Data Mapping: The converter identifies key-value pairs in a JSON file (e.g., "name": "John Doe") and maps them to standard VCF fields (e.g., FN:John Doe).
