Automated MySQL to Google Sheets Sync with Duplicate Prevention

This n8n workflow automates the extraction and synchronization of new records from a MySQL database table (e.g., fifa25_customers) to a Google Sheet. It triggers every 15 minutes via a schedule node, queries for unsynced rows where sync=0, checks for existing records in the sheet to avoid duplicates, appends new data mapping fields like id, name, phone, birthdate, email, region, gender, and datetime, and finally updates the MySQL table to set sync=1 for processed rows.

Key benefits include reliable data backup, effortless reporting, and lightweight ETL without manual intervention. It prevents redundant entries, ensuring data integrity, and is fully annotated with sticky notes for easy customization and onboarding. Ideal for marketers syncing leads, ops teams exporting user data, analysts tracking submissions, or any scenario needing periodic database-to-sheet transfers.

Setup is straightforward: prepare a Google Sheet with matching columns, ensure MySQL has a sync column, connect credentials for MySQL and Google Sheets OAuth2, and activate. Optional enhancements include custom filters or transformations, making it versatile for CRM, surveys, or registrations.
