Why Convert VCF to JSON?
JSON is the format you want when contact data is heading into code: scripts, apps, databases, or APIs. This tool parses each vCard in the file and emits a clean JSON array of contact objects with structured fields.
Every contact keeps its detail: names (first, last, middle, prefix, suffix), organization, title, emails and phones as typed arrays, URLs, structured addresses, birthday, and notes — far richer than a flat CSV.
Conversion is fully client-side, so contact data never leaves your machine — safe to use even with production data exports.
Key Features
About VCF and JSON Formats
VCF (vCard Contact File)
VCF (vCard) is the standard format for electronic business cards. Stores contact information like name, phone, email, and address.
JSON (JSON)
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and machines to parse.
Common Use Cases
- Load an address book export into a script or application
- Inspect exactly what data a .vcf file contains
- Migrate contacts into a database with a JSON import step
- Diff two contact exports programmatically
Frequently Asked Questions
What does the JSON output look like?
A pretty-printed JSON array with one object per contact. Emails and phones are arrays of {type, value} objects, and addresses are structured objects with street, city, region, postal code, and country.
Are multi-contact VCF files supported?
Yes — every vCard in the file becomes an element of the JSON array.
Can I convert the JSON back to VCF later?
Yes. The JSON to VCF converter on this site accepts exactly this format, so the round trip works without editing.
