In this video, I show you how to automate your Retell AI → n8n → Google sheet workflow without using an AI agent inside n8n. <br /><br />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: <br /><br />Full name <br /><br />Email <br /><br />Phone <br /><br />Appointment date & time <br /><br />But that AI agent costs money. <br /><br />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. <br /><br />What you’ll learn: <br /><br />✅ How Retell AI sends data via webhook into n8n <br />✅ Why the n8n AI agent is not needed <br />✅ How to extract clean data using a simple JSON code function <br />✅ How to send the processed data to Google sheet <br />✅ Complete workflow explanation <br />✅ Free code included <br /><br />This tutorial is perfect for clinics, agencies, and automators who want to save money and simplify their workflow. <br /><br />💡 Click on below link to visit my official website to get JSON code: <br /><br />https://getiknowledge.com/2025/12/08/save-money-process-retell-ai-webhook-data-in-n8n-without-any-ai-agent/ <br /><br /><br />#getinformationandknowledge
