How to download FamilyTreeDNA raw data

  • Turn on two-factor authentication in your account settings — downloads need it.
  • Open Results & Tools → Autosomal DNA → Download Raw Data.
  • Choose “Build 37 Concatenated Raw Data” — a .csv.gz file downloads.
  • Upload that file here. Raw data of kits transferred to FTDNA from other companies can't be downloaded.

What the converter does

  • The format is detected automatically: this page takes VCF as well as AncestryDNA, MyHeritage and FamilyTreeDNA raw data.
  • Takes the .csv.gz file as is — no need to unpack it.
  • The concatenated Build 37 file with a repeated header works too.
  • Genotypes and no-calls (--) are kept as is; only the file format changes.

Where can you use the result?

The 23andMe format is accepted by GEDmatch, Genomelink, Genetic Genie, Living DNA, tellmeGen and other services — see the catalog on the home page. FamilyTreeDNA accepts original files only.

Frequently asked questions

How do I download FamilyTreeDNA raw data?

Turn on two-factor authentication, then Results & Tools → Autosomal DNA → Download Raw Data → Build 37 Concatenated Raw Data. A .csv.gz file downloads.

The .csv.gz file won't open. Do I need to unpack it?

No. Upload it here as is — the converter unpacks it, including the concatenated file with a repeated header.

Can I download data of a test transferred to FamilyTreeDNA?

No, FamilyTreeDNA doesn't let you download data of transferred kits. Use the original file from the company that ran your test.

Why convert if services accept this format?

If a service accepts your original file, upload the original. Conversion helps when a service or a program only reads the 23andMe format, or when you want files from different companies in one layout.

Is it safe?

Yes. The file is processed right in your browser, on your device: it is never sent to our server or shared with anyone. Nothing is kept after you close the tab.
