Get started with Google Sheets in n8n

A hands-on starter workflow that teaches beginners how to:

Pull rows from a Google Sheet

Append a new record that mimics a form submission

Generate AI-powered text with GPT-4o based on a “Topic” column

Write the AI output back into the correct row using an update operation

Along the way you’ll learn the three essential Google Sheets operations in n8n (read → append → update), see how to pass sheet data into an OpenAI node, and document each step with sticky-note instructions—perfect for anyone taking their first steps in no-code automation.

0️⃣ Prerequisites - Google Sheets 1. Open Google Cloud Console → create / select a project. 2. Enable Google Sheets API under APIs & Services. 3.
