How to Use ChatGPT in Google Sheets (Step-by-Step Guide)

Why This Matters

Google Sheets remains one of the most widely used workplace tools, with over 2 billion users worldwide relying on it for reporting, collaboration, and productivity. But Sheets on its own can only go so far. By integrating ChatGPT directly into your spreadsheet, you can automate repetitive tasks, generate text, analyze data, and even brainstorm – all without leaving the grid.

As AI becomes a mainstream productivity tool in 2025, this workflow is quickly becoming one of the most searched tutorials for professionals, freelancers, and students alike.

How the Integration Works

There are two main ways to connect ChatGPT with Google Sheets:

1. Through an Add-on

• Tools like GPT for Sheets and Docs (available in the Google Workspace Marketplace) let you call ChatGPT directly inside a cell.
• This requires linking your OpenAI API key.

1. Via Apps Script

• Google’s built-in scripting tool allows you to write a short script that connects to the OpenAI API.
• This gives more customization power – ideal for advanced users.

Step-by-Step Setup (Add-on Method)

1. Open Google Sheets.
2. Go to Extensions > Add-ons > Get add-ons.
3. Search for “GPT for Sheets and Docs” and install it.
4. Once installed, go to Extensions > GPT for Sheets and Docs > Set API Key.

• Paste your OpenAI API key (available from platform.openai.com).

1. In any cell, type a formula like:

   =GPT("Summarize this text: " & A2)

• If A2 contains a paragraph, ChatGPT will return a concise summary.

Example Use Cases

Example formulas and AI-generated outputs inside Google Sheets.

• Brainstorming ideas

• Data cleaning
  =GPT("Standardize the company names: " & A2:A20)
• Customer response drafts
  =GPT("Write a polite reply to this customer complaint: " & A2)
• Summarization
  =GPT("Summarize this email in 50 words: " & A2)

Benefits

• Saves time: Automates repetitive text-based tasks.
• Enhances productivity: Lets teams focus on insights instead of admin work.
• Accessible: No coding required for the add-on method.

Challenges & Ethics

• Cost: Each API call consumes credits. Heavy use may increase costs.
• Accuracy: AI outputs require human review, especially in business-critical contexts.
• Privacy: Avoid sending sensitive or confidential data to external APIs.

Outlook

With workplace AI adoption rising fast – 77% of companies are either using or exploring AI tools in 2025 (PwC) – ChatGPT integrations in tools like Sheets are no longer just “nice-to-have.” They’re becoming essential for competitive productivity.

Practical Takeaways

• Start with the add-on method for quick use.
• Switch to Apps Script if you want more advanced customization.
• Always verify AI outputs before sharing or publishing.
• Track usage to manage costs effectively.
