Checking publication status...LOCAL CONTACT CONVERTER / CSV TO VCF
CSV to VCard
Convert a header-based contact CSV into one UTF-8 vCard 3.0 file using practical name, email, phone, company, title, address, and website aliases.
Processed in this browserOne UTF-8 .csv file up to 5 MB and 1,000 contact rows. Each row needs at least a name, email, or phone.
CSV - 1,000 contacts
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
One UTF-8 .csv file up to 5 MB and 1,000 contact rows. Each row needs at least a name, email, or phone.
Plain-language method
How headers map to contact properties
Headers are normalized and matched to conservative aliases such as full_name, first_name, last_name, email, phone, organization, title, address, and website. Each valid row becomes one vCard 3.0 record.
- 01Choose a valid source
Use a header row and consistent columns. At least one identifying name, email, or phone header must exist.
- 02Review the conversion choices
Choose the actual delimiter. Unknown columns are ignored rather than copied into ambiguous custom properties.
- 03Inspect the separate result
The combined download ends in _nirmion_tools_contacts.vcf and can be reviewed before import into a contact application.
Useful when
Practical jobs this tool handles
- Import a clean spreadsheet contact list into a phone.
- Turn a registration export into portable contact cards.
- Prepare a bounded contact migration without a cloud converter.
Before converting
Test before a large import
- Convert a small sample and import it into the target address book.
- Check country codes and phone formatting.
- Back up the target address book before bulk import.
Know the boundary
Header aliases are deliberately conservative
Unknown or custom columns are omitted, and the tool does not deduplicate contacts. Review the generated cards before importing them into a live address book.
Quick answers
Questions before you convert
Clear headers produce the most predictable contacts.
Which headers are recognized?
Common aliases for full and split names, email, phone, organization, title, address, and website are supported.
Are duplicate rows removed?
No. Every valid non-empty row becomes one card so the tool does not make identity decisions for you.
Can I add photos or groups?
Not in this basic vCard 3.0 export. Add richer properties in a contact application after review.
