How to bulk-add contacts to Android from a CSV

Option 1 — through Google Contacts (recommended)

Importing through your Google account syncs the contacts to every Android device you own, and Google's import tool is the most forgiving.

1. Open the CSV to Android converter, drop in your file, and choose Google Contacts CSV as the output.
2. Check the column mapping, then download the CSV.
3. Go to contacts.google.com → Import (in the left menu) → Select file, and pick the downloaded CSV.
4. The contacts appear under a new label and sync to your phone within minutes.

Option 2 — directly on the phone with a .vcf

Choose Android as the output instead, download the .vcf, and open it on the phone — the Contacts app will offer to import all of them. This is handy when you don't want the contacts in a Google account (they can be saved to the device or a Samsung account instead).

Phone number formatting

Android matches and merges contacts by phone number, so consistent formatting matters. Use the "Normalize numbers to international format" option and pick your country code — numbers like 08123 456789 become +91 8123 456789 and merge correctly with existing entries.
