What You Need Before Integrating ChatGPT Into Google Sheets

Before you can start prompting ChatGPT inside your spreadsheet or auto-generating content in real time, there are a few essential tools and accounts you’ll need to have in place. This section helps you set the foundation — even if you're not technical. 

OpenAI Account with API Access

To connect ChatGPT to your Google Sheet, you'll need an API key, and that comes from OpenAI.  

• Head to platform.openai.com  

• Sign up or log in  

• Navigate to your API dashboard and generate a key. This key acts like your access pass to ChatGPT’s brainpower — it's what allows the spreadsheet to send and receive data from OpenAI.  

Google Account with Sheets Access 

Since this setup runs inside Google Sheets, you need to be logged into a Google Account. Make sure you have:  

• Access to Google Sheets  

• Permission to install add-ons (especially if you're using a work account)  

Install the “GPT for Sheets and Docs” Extension 

Go to the Google Workspace Marketplace and search for:  

• GPT for Sheets and Docs. This is the add-on that connects your spreadsheet to ChatGPT. 

• Once installed, it adds new functions like =GPT() or =GPT_FILL() directly into your Google Spreadsheet — so you can generate answers, summaries, or content without leaving the page.  

Your API Key Setup Inside Sheets  

After installing the add-on:  

• Open any Google Sheet  

• Click Extensions > GPT for Sheets and Docs > Set API Key  

• Paste in your OpenAI key and save  

This one-time setup enables the add-on to talk to OpenAI in the background and return responses from ChatGPT when you run formulas.   

(Optional) Watch a Quick Video Tutorial  

If you’re unsure about installation or setup, there are plenty of short video tutorials available that walk through this process. It helps to see it in action before you start prompting ChatGPT in your own Google Sheet.

Install the GPT for Sheets and Docs Add-on

Start by heading to the Google Workspace Marketplace and searching for “GPT for Sheets and Docs.” Click Install and grant the necessary permissions. Once added, it’ll appear under your Extensions menu.

Numerous users don’t need to worry about technical complexity here; Numerous providers provide step-by-step setup guides and even automate part of this installation when linked to a shared Google account.  

Generate and Insert Your API Key

Go to your OpenAI dashboard and copy your API key. Then: 

• In your Google Sheet, click Extensions > GPT for Sheets and Docs > Set API Key. 

• Paste your key and click save. 

Now, your sheet can communicate with ChatGPT’s brain in real time. With Numerous, however, you can skip manually crafting your own formulas. 

Numerous lets you trigger pre-written prompts like “Summarize this table,” “Write a LinkedIn caption,” or “Turn this into a blog intro” — all without memorizing commands.  

Try Your First GPT Formula

You’re now ready to prompt ChatGPT. 

Examples of basic formulas: =GPT("Write a tweet about eco-friendly skincare") =GPT("Summarize the text in cell A2") =GPT_FILL(A2:A10, "Write a caption for each product") 

For more complex prompts, you can reference other cells, concatenate strings, or use GPT_LIST for multiple outputs. 

Numerous simplifies this even further. Instead of writing formulas, you can click once to:

• Auto-generate social media captions based on product names in a column. 

• Convert bullet points into email copy. 

• Summarize customer feedback into insights for pitch decks. 

This is particularly helpful for teams who want speed and consistency across thousands of entries.  

Use Bulk Tools to Scale Your Workflow

Here’s where GPT becomes a true productivity booster. Whether you're building content calendars, writing meta descriptions, or cleaning data, you can: 

• Drag formulas down columns 

• Use GPT_FILL() to auto-complete rows based on instructions

• Apply logic to generate variants (e.g., 3 ad headlines per cell) 

If you're using Numerous, this entire process is even more efficient. Numerous is optimized for bulk content generation inside Google Sheets, and includes built-in templates for: 

• Email campaigns 

• YouTube titles 

• Product descriptions 

• TikTok scripts

It understands your use case (e.g., you’re creating social media content, writing bios, or preparing academic summaries). It automatically structures the outputs — no need to tweak your prompts over and over.  

Save and Test

Try refreshing your sheet or running a small batch of GPT functions to see if that resolves the issue. If you get errors:

• Double-check your API key 

• Reduce input length 

• Start with shorter prompts 

Numerous provide helpful inline explanations for common errors, like token limits or formatting issues. It even offers prompt suggestions when your first try doesn't return the result you expected.

6 Practical Use Cases of ChatGPT in Google Sheets

1. Generate Social Media Captions in Bulk

Managing multiple products, posts, or campaign assets can chew up hours. Writing social captions manually? That’s the slowest way to get it done. 

Once you integrate ChatGPT into your Google Sheets, you’ll be able to write social media captions at lightning speed. Here’s how it works: 

• Add your product titles or blog headlines in one column (e.g., Column A). 

• In Column B, use =GPT_FILL(A2:A20, “Write a short, engaging Instagram caption for each item”). 

You can even adjust the tone to suit your preferences, such as professional, fun, or Gen Z.

Pro tip

Numerous.ai makes this even easier with built-in templates like: 

• “Instagram captions from product titles” 

• “Turn blog headers into X threads.” 

• “Write TikTok hook lines from a one-line brief.”

2. Summarize Large Texts Into Actionable Insights

Surveys, customer reviews, and feedback can help you improve your products and services, but only if you can get to the insights quickly. Instead of reading through hundreds of lines of long-form text, you can summarize them directly inside Sheets with ChatGPT. Here’s how it works: 

• Paste your long-form text in Column A. 

• In Column B: =GPT(“Summarize the feedback in cell A2 in 3 bullet points”). 

This is ideal for research teams, support analysts, or UX designers seeking to identify patterns. With Numerous, you just select your column, choose “summarize all rows,” and it does the rest — structured, formatted, and ready to present.

3.  Write Email Copy from a Spreadsheet

If you’re doing email marketing, outbound sales, or newsletters, this will save you hours. Here’s how it works: 

• Fill out fields like customer name, offer, and product in separate columns. 

• Use GPT to write the message: =GPT(“Write a promotional email to {{name}} about {{product}} with a discount”) 

• You can even create multiple versions per row to A/B test. 

Numerous is particularly good here — it comes with an “Email Writer” tool that lets you bulk-generate personalized emails across your list.

4. Create SEO Meta Descriptions from Product Listings

Let’s say you’re building an e-commerce store. Instead of writing meta descriptions manually, you can use ChatGPT to do it in seconds. Here’s how it works: 

• Column A = product title 

• Column B = product category 

• GPT formula in Column C: =GPT(“Write a 155-character SEO meta description for a {{category}} product called {{title}}”). 

It saves effort while keeping your content optimized for search. Numerous already has a “meta description” bulk tool built in — no formulas, just click, generate, and done.

5. Translate Content or Product Descriptions

Need your content in multiple languages? ChatGPT can translate instantly. Here’s how it works: 

• Column A = original description 

• In Column B: =GPT(“Translate this into Spanish: “ & A2). 

For global teams or multilingual audiences, this can localize your content without hiring extra help. Numerous even allows batch translation with proper formatting — you just select the language, and it handles the output.

6. Turn Messy Data Into Clear, Human-Sounding Summaries

Let’s say you have a row of metrics: open rates, traffic, and conversion. Instead of copying into a doc and writing a report, let ChatGPT turn it into a summary. Here’s how it works: 

• All your metrics go in one row (e.g., A2 to E2).

•  In a new cell: =GPT(“Summarize the weekly marketing performance from these values: “ & A2 & “, “ & B2 & “, “ & C2 …) 

The result? A natural-language paragraph you can drop into a Slack message or deck. With Numerous, you just use the “Weekly Summary” or “Campaign Wrap-Up” smart prompt — no setup, no formula-writing, just click and go.

Numerous is an AI-powered tool that enables content marketers, E-Commerce businesses, and more to automate tasks many times over through AI, such as writing SEO blog posts, generating hashtags, mass categorizing products with sentiment analysis and classification, and many more functions by simply dragging down a cell in a spreadsheet.
