XLSX - 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

Plain-language method
How Excel to VCard works
The browser reads stored worksheet values, maps conservative aliases for name, first name, last name, email, phone, organisation, title, address, and website, validates that each row identifies a contact, escapes vCard text, and writes one VERSION:3.0 record per row.
- 01Choose a valid source
Use headers such as full_name, first_name, last_name, email, phone, organization, title, address, or website. Each data row needs a name, email, or phone.
- 02Review the conversion choices
Worksheet number follows workbook tab order, including hidden tabs. Formulas are not recalculated.
- 03Inspect the separate result
The .vcf download combines all accepted contacts. Import it into a test or approved address book only after reviewing the records.
Useful when
Practical jobs this tool handles
- Prepare a reviewed contact sheet for address-book import.
- Move approved spreadsheet contacts into a portable VCF.
- Create deterministic vCard fixtures.
Before converting
Check the source and destination rules
- Verify headers use supported aliases.
- Remove rows without a name, email, or phone.
- Back up the destination address book before import.
Know the boundary
Know what the destination format cannot keep
The tool creates simple vCard 3.0 records and does not support photos, groups, labels, custom properties, multiple repeated values, or provider-specific metadata.
Quick answers
Questions before you convert
The conversion contract is deliberately explicit.
Which row supplies headers?
The first row of the selected worksheet.
Are formulas evaluated?
No. Only stored results are used when present.
Can I import the result directly?
Yes in software that accepts vCard 3.0, but review a small test import first.
