How to Download Your 23andMe Raw Data File in 2025

Step by step guide to download your 23andMe raw DNA file in 2025, plus tips to analyze it privately on your own device.

Why download your raw data

Your 23andMe account includes a raw text file listing your genotypes at thousands of SNP positions. Downloading it gives you more freedom to explore traits with tools that keep your data on your device.

What you get:

  • A plain text file with columns like rsid, chromosome, position, genotype
  • A header with comments that describe the build and format
  • A file size that is usually a few megabytes

Step by step

  1. Sign in to your 23andMe account
  2. Go to Settings - Data - Browse Raw Data
  3. Find the “Download Raw Data” or “Request your data” link
  4. Confirm password and two factor if prompted
  5. When the email arrives, follow the secure link and download the .txt file

The file is a plain text table, usually a few megabytes in size. Keep it somewhere safe and private.

Verify the file

Before using the file, do a quick integrity check locally:

head -n 5 23andme_raw.txt
wc -l 23andme_raw.txt
rg "^rsd+" -n 23andme_raw.txt | head -n 3   # or: grep '^rs' 23andme_raw.txt | head -n 3

You should see a commented header and many lines starting with rs followed by chromosome, position, genotype.

Store it safely

  • Keep a single master copy in a private folder or encrypted volume
  • Avoid email or chat attachments for raw files
  • If you sync to cloud storage, use an account you control and understand
  • Remove old copies and empty the trash after you make a new backup

Analyze your file privately

If you want to explore traits without uploading anywhere, try a browser based approach that processes everything locally:

Tips for safe handling

  • Store the file in an encrypted drive or password manager vault
  • Avoid emailing the raw file to yourself
  • Delete old copies you no longer need
  • If you do upload to a service, read their policy first

Troubleshooting

  • If you cannot find the download link, check your account permissions and the help center
  • If the file will not open, verify it is plain text and not a compressed archive
  • If the link expired, request a new download from the data section
