Power Up Your Workflow with Google Apps Script + Gemini

Automate, accelerate, and innovate inside Google Workspace

Today, AI and automation are finally meeting where people already work: Google Workspace. In my latest presentation, Google Apps Script & Gemini — Power Up, I explored how anyone—beginner or advanced—can use simple JavaScript plus Google’s Gemini models to build smart tools directly inside Sheets, Docs, Gmail, and Drive.

If you’re curious about AI-powered automation or you’re ready to modernize your workflow, this guide highlights everything we covered.


🔧 What Is Google Apps Script?

Google Apps Script is a cloud-based JavaScript platform that lets you automate and extend Google Workspace.
As shown in the presentation (page 2) Google Apps Script and Gemini P…, Apps Script can:

  • Automate repetitive tasks
  • Connect Sheets, Docs, Drive, Calendar, and Gmail
  • Build custom menus, triggers, web apps, and add-ons
  • Integrate APIs—now including Gemini

Best of all? No servers. No setup. Just open Extensions → Apps Script and start coding.


💡 What You Can Build (Examples from the Presentation)

Pages 3–5 of the deck showcase the wide range of real-world use cases Google Apps Script and Gemini P…:

✅ Automation

  • Convert Sheets → PDF
  • Schedule daily emails
  • Run processes on timers

✨ Custom Sheet Functions

Imagine typing:
=GETWEATHER("Miami")
=CURRENCYCONVERT(100, "USD", "EUR")
(Yes, you can build these!)

📝 Forms & UI Tools

  • Pre-fill Google Forms
  • Build interactive sidebars and menus
  • Create dashboards and micro web apps

📧 Gmail Automation

Pages 12–13 introduce a clever Apps Script + OCR workflow Google Apps Script and Gemini P…:

  • Extract totals from PDF invoices
  • Summarize them
  • Email the results

A simple solution for accounting or finance teams drowning in documents.


🔗 Fetch External API Data

Pages 14–15 show how Apps Script connects to public APIs like RandomUser API Google Apps Script and Gemini P…:

  • Fetch 50 users
  • Parse names, emails, phones
  • Insert automatically into Sheets

This is ideal for mock data, prototyping apps, or practicing API integration.


🤖 Gemini + Apps Script: Your AI Workflow Begins

The second half of the presentation dives into connecting Sheets, Docs, Drive, and Gmail to Gemini.

Pages 16–20 show:

⚙️ The Core callGemini_() Helper

A simple REST call that:

  • Sends a prompt

🌱 How I Started with Apps Script

(Page 38) Google Apps Script and Gemini P…
In 2015, I was trying to capture tweets into a Google Sheet—without a server. Apps Script solved that for me. Since then, I’ve built tools, taught thousands of developers, and explored how Apps Script + AI can empower everyone.
