In this video, I show you how to automate your Retell AI → n8n → Google sheet workflow without using an AI agent inside n8n.
Retell AI sends a large and complex JSON payload when someone calls your clinic. Many people use an extra AI agent in n8n to summarize and extract key fields like:
Full name
Email
Phone
Appointment date & time
But that AI agent costs money.
Instead, I replaced it with a free JSON function inside n8n that extracts the exact fields you need — no AI usage, no credits, no cost.
What you’ll learn:
✅ How Retell AI sends data via webhook into n8n
✅ Why the n8n AI agent is not needed
✅ How to extract clean data using a simple JSON code function
✅ How to send the processed data to Google sheet
✅ Complete workflow explanation
✅ Free code included
This tutorial is perfect for clinics, agencies, and automators who want to save money and simplify their workflow.
