Automated MySQL to Google Sheets Sync with Duplicate Prevention

📝 Sync MySQL Rows to Google Sheet

Description:

This n8n template automates the process of syncing new records from a MySQL database table into a Google Sheet, ideal for reporting, backup, or lightweight dashboards.

It is designed for teams or individuals who need to periodically export new data rows from a custom database (e.g., CRM, registrations, surveys) into a structured Google Sheet for further analysis, sharing, or archiving—without duplicates.

🛠️ What This Workflow Does:

Runs every 15 minutes** via a schedule trigger. Selects unsynced rows** (sync = 0) from a MySQL table (fifa25_customers). Checks if records exist** to prevent unnecessary writes. Appends records to a Google Sheet**, mapping fields like name, email, phone, gender, and more. Updates the MySQL table** to mark those rows as synced (sync = 1) to avoid reprocessing. Fully annotated using sticky notes for easier understanding and onboarding.

📋 Setup Instructions:

Create or select a Google Sheet and make sure the columns match the following:

id, name, phone, birthdate, email, region, gender, datatime Ensure your MySQL table (fifa25_customers) has a sync column (default = 0 for new rows). Connect your MySQL and Google Sheets credentials inside n8n. (Optional): Add custom filtering or column transformations as needed.

✅ Best Practices Followed:

Uses IF node to prevent unnecessary processing Updates source database to avoid duplicates Includes sticky notes for clarity All columns are explicitly mapped Works out-of-the-box on any n8n instance with proper creds
