For business use, the safest way to
import contacts from Excel to Android is to follow a structured and controlled process. Start by validating the Excel data, removing duplicates, and ensuring correct formatting. Convert the file into CSV and import it into Google Contacts, which offers secure syncing and backup. This method protects business contact data and ensures consistency across devices.
When working with large or frequent contact updates, some businesses use tools like MailConverterTools Excel to vCard Converter to convert Excel files into vCard format before importing them into Android. This helps maintain data integrity, avoid manual errors, and ensure that contacts are transferred securely and accurately.
