n8n Google Sheets Tutorial – Connect Forms, APIs, and Databases in Minutes

Hey everyone :waving_hand:

I’m excited to share my latest n8n tutorial video, where I dive deep into one of the most versatile integrations — Google Sheets. Whether you’re just starting out with n8n or already building complex automation workflows, this tutorial will show you how to turn Google Sheets into a simple yet powerful database for your automation projects.

What You’ll Learn in This Video

In this hands-on guide, I walk through everything step-by-step — from authentication setup to practical real-world examples:

  1. Setting up Google Sheets credentials (OAuth 2.0)

    • How to enable the Google Drive and Sheets APIs in Google Cloud Console

    • How to generate and connect client ID & secret in n8n

    • Common pitfalls and how to fix OAuth redirect errors

  2. Creating your first workflow – Write Mode

    • Build a user contact form in n8n using the Form Trigger node

    • Append each form submission automatically to Google Sheets

    • Store name, email, company, and message fields dynamically

    • Use Sheets as a lightweight CRM or lead-tracking database

  3. Building the second workflow – Read Mode

    • Use a form to search product information by SKU

    • Retrieve the corresponding row from Google Sheets in real time

    • Enrich API calls or chatbot responses using live data

    • Demonstrate how n8n can treat Sheets like a mini API backend

Why This Tutorial Matters

Many new n8n users start their automation journey with Google Sheets — it’s free, flexible, and integrates with almost everything. But setting up OAuth and mapping data fields correctly can be confusing at first.

This video aims to demystify the setup and help you build your first end-to-end workflow confidently.

By the end, you’ll have:

:white_check_mark: A contact form that logs data into Google Sheets automatically

:white_check_mark: A working inventory lookup workflow using the “Get Row” operation

:white_check_mark: A solid foundation to extend this logic to any data-driven automation (email, CRM, chatbot, or API).

Who This Is For

  • Beginners learning how to connect external services to n8n

  • No-code creators who want to manage data easily

  • Developers prototyping fast workflows

  • Anyone who wants to use Google Sheets as a quick, serverless database

Let’s Build Together

I’d love to hear what you think — did you find this walkthrough helpful?

Also, share your favorite Google Sheets use cases in n8n — maybe:

  • Tracking expenses automatically

  • Logging chatbot conversations

  • Enriching product data for APIs

  • Auto-generating reports or invoices

Your feedback will help me decide what to cover next — I’m planning a follow-up video on connecting Google Sheets with Gmail and AI tools in n8n (for smart replies or automated summaries).
