This workflow is a hands-on tutorial for the Code node in n8n, covering both basic and advanced concepts through a simple data processing task.

Provides Sample Data: The workflow begins with a sample list of users. Processes Each Item (Run Once for Each Item): The first Code node iterates through each user to calculate their fullName and age. This demonstrates basic item-by-item data manipulation using $input.item.json. Fetches External Data (Advanced): The second Code node showca

Automate Google Form Tracking & Gmail Alerts via n8n

Boost your administrative efficiency with this comprehensive n8n automation suite designed to bridge the gap between data collection and actionable insights. This workflow transforms standard Google Form submissions into a high-performance management ecosystem. Instead of manually checking spreadsheets, the system triggers instantly upon form submission, updating a centralized Google Sheets dashboard with real-time statistics while simultaneously executing conditional logic via the Code node. The automation intelligently distinguishes between new registrants and follow-ups, triggering personalized Gmail acknowledgments for immediate engagement. Furthermore, it incorporates a sophisticated reminder logic to ensure no student or lead falls through the cracks. By leveraging Webhook and Respond to Webhook nodes, the suite maintains a low-latency connection between your front-end forms and back-end database. This setup eliminates manual data entry errors, reduces response times by up to 90%, and provides stakeholders with a live visual overview of registration trends. It is an essential toolkit for any organization looking to scale their intake process without increasing headcount. **Common Use Cases:** - Educational Workshop & Course Enrollment Management - Automated Event Registration with Instant Attendee Confirmation - Customer Inquiry Routing and Lead Nurturing Pipeline
