Looking for a CoolUtils CSV to vCard Alternative?
The practical difference between converters is not the output — a valid .vcf is a valid .vcf — it is where your contact list goes to get converted. As of August 2026 their online converter page describes an upload-to-their-servers flow. The converter below does the entire job in your browser: your CSV is never uploaded anywhere, and you can prove it by going offline before you convert.

.csv, .xlsx, .xls or .json — up to 10 MB / 50,000 contacts, never uploaded.
The core difference: where your contact list goes
CoolUtils describes its own online converter plainly: step one is “Upload Your File”, and its security note says uploads are encrypted in transit and “processed in data centers”, with both files “deleted automatically from our servers” after conversion (their wording, as of August 2026). That is the standard server-side model, described honestly — your contact list makes a round trip to their infrastructure, protected by their policies.
This site uses the other model. The parser and vCard generator are JavaScript that runs on your device; there is no upload endpoint in the page at all. The privacy claim is not a policy you trust but an architecture you can check: open your browser's network tab while converting, or load the page and switch off your connection — the conversion still completes.

What CoolUtils does well
An honest comparison cuts both ways. As of August 2026 their site still presents a converter suite covering far more format pairs than this site ever will, and describes a paid desktop tool that batch-converts entire folders from the command line — something a browser tool cannot match. If you convert many kinds of files on Windows and want one installed program for all of it, that is a reasonable choice. This site is the opposite trade: one job — contact lists between CSV, Excel and vCard — done carefully, in the browser, with the vCard spec followed properly and nothing uploaded.
CoolUtils alternative — frequently asked questions
What is the main difference between this converter and CoolUtils?
Where the conversion happens. As of August 2026 their online converter page describes the flow as 'Upload Your File' and says uploads are 'processed in data centers'. This converter is JavaScript running on your device: the CSV is parsed and the vCard generated in your browser tab, and there is no upload endpoint at all.
Doesn't CoolUtils delete uploaded files afterwards?
As of August 2026 their privacy note says files are deleted automatically from their servers after conversion. That may well be true — but it is a promise you have to take on trust. With a client-side converter there is nothing to delete, because the file never left your machine. You can verify that yourself: load this page, disconnect from the internet, and the conversion still works.
Is this converter really free, with no file limits?
The converter is free, with no queue and no premium tier. It enforces safety limits of 10 MB per file, 50,000 rows, 200 columns and 1,000,000 cells. Column mapping, preview and vCard 2.1/3.0/4.0 output are all included.
When would CoolUtils be the better choice?
As of August 2026 their site sells a paid Total Excel Converter for Windows desktop batch conversion from the command line, and lists many more format pairs than this site does. This site does one job — contact-list conversion between spreadsheet formats and vCard — and does it without uploads.
Why does it matter whether a contact list is uploaded?
A contact list is not only your data — it is the names, phone numbers and email addresses of everyone you know. Sending it to a third-party server should be the exception, not the default a converter quietly assumes. The no-upload model removes the question entirely.
