No file upload

This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.

Original stays unchanged

The converter creates a separately named output. It never writes back into the source file.

Bounded work

Plain-language method

How vCard fields become JSON properties

Nirmion identifies complete vCard records, decodes common escaped text, projects full name, first name, last name, email, phone, company, title, address, and note into stable snake-case properties, applies the selected empty-field rule, and serializes contacts in their original order.

01
Choose a valid source
Use a UTF-8 vCard export with complete record markers. Keep the original because photos, custom properties, multiple repeated values, and provider extensions are outside this common-field projection.
02
Review the conversion choices
Omit empty fields creates smaller records; Include writes all nine properties for a stable shape. Indentation affects readability only.
03
Inspect the separate result
The download ends in _nirmion_tools_contacts.json. It contains ordinary JSON text and no embedded contact photos or account credentials.

Useful when

Practical jobs this tool handles

Review common contact fields before migration.
Create approved address-book fixtures for an application.
Move a simple VCF export into a JSON workflow.

Before converting

Protect personal contact data

Confirm you have permission to process the contacts.
Keep the original VCF for unsupported fields.
Review the JSON before sharing or importing it.

Know the boundary

This is a common-field projection

Multiple emails or phones, embedded photos, groups, labels, custom properties, and provider extensions may not be represented. The original vCard remains the complete source.

Quick answers

Questions before you convert

The output is designed for clear common records.

Which properties are included?

Full name, first name, last name, email, phone, company, title, address, and note.

Are contact photos included?

No. Binary photos and custom attachments are deliberately omitted.

Does Nirmion sync my contacts?

No. It reads the chosen file in this browser and creates a separate JSON download.
