7 Best AI Tools for Google Sheets (2026)

Google Gemini (built-in)

Google's own AI lives inside Sheets now, and it's the obvious starting point. The Gemini side panel takes plain English and turns it into formulas, charts, and pivot tables. The =AI() function (you can also use =Gemini()) runs prompts directly in cells, which means you can process text data the same way you'd use SUM or AVERAGE.

I asked it to "create a pivot table showing revenue by region, sorted highest to lowest" on a 5,000-row sales dataset. It read the column headers, built the pivot, and dropped it into a new sheet. Took maybe 10 seconds. That's the kind of task that makes you wonder why you ever did it manually.

The =AI() function is where things get interesting. Put =AI("Categorize this feedback as positive, neutral, or negative", A2) in a cell and drag it down a column. Each row gets classified. For light text processing, this replaces what used to require a dedicated add-on.

Included with Google Workspace Business Standard and above ($14/user/month). Personal accounts need Google One AI Premium ($19.99/month). If you're already on Workspace, you're already paying for it.

The downsides: =AI() processes row by row, so it drags on large datasets (500+ rows gets noticeably slow). Formula suggestions sometimes reference wrong cell ranges, especially in complex sheets with multiple tabs. And you can't customize the underlying model or adjust temperature the way you can with add-ons.

GPT for Sheets and Docs

GPT for Sheets is the most popular AI add-on in the Workspace Marketplace, and for good reason. It gives you custom functions: =GPT(), =GPT_CLASSIFY(), =GPT_EXTRACT(), =GPT_TRANSLATE(), =GPT_TABLE(). Each one does exactly what the name suggests.

The power move is batch processing. I've used =GPT_CLASSIFY() to categorize 3,000 customer support tickets into 8 categories in about 20 minutes. Doing that manually would have been a full day. =GPT_EXTRACT() pulls structured data out of messy text, like pulling company names and dollar amounts out of unformatted email bodies.

The pricing model switched to usage-based credit packs starting at $29. You also need your own OpenAI API key, so there's a separate cost for API calls on top. Processing 10,000 rows can run $5-50 depending on the model and prompt length. The functions also recalculate when the sheet refreshes, which racks up charges if you're not careful.

Worth the complexity for anyone doing serious bulk text work. Overkill for writing formulas.

Numerous.ai

Numerous.ai dropped its prices significantly. The Starter plan is now $5/month, which makes it the cheapest way to get bulk AI processing in Sheets with no API key required.

It's built for marketing teams. Generate hundreds of product descriptions, meta tags, email subject lines, or ad variations directly in your spreadsheet. The =AI() function works similarly to Gemini's, but Numerous handles large batch operations (5,000+ rows) more smoothly and offers both GPT and Claude model options.

Sentiment analysis, SEO content generation, and data enrichment are the core use cases. If you manage a product catalog or run content operations through spreadsheets, Numerous fits that workflow well.

At $5/month it's hard to argue with the value. The Professional plan at $49/month adds team features and higher limits. For most individual users, the Starter tier covers it.

The limitation: it's built for text processing, not data analysis or formula generation. If you need help writing QUERY functions, Gemini or ChatGPT will serve you better.

SheetAI

SheetAI keeps it simple. Install the add-on, get AI functions for text generation, data cleaning, and formula creation. No API key required. The tool handles the AI backend.

The =SHEETAI() function generates text, summarizes, translates, and transforms data. A sidebar formula generator takes plain English and returns ready-to-use formulas. Template prompts cover common tasks like email drafting and categorization.

At $5.99/month for Pro, it's the easiest entry point for someone who wants basic AI in Sheets without dealing with API keys or credit systems. The models aren't as strong as what GPT for Sheets runs (you'll notice on complex classification tasks), and the function library is smaller. But for straightforward text processing and formula help, it does the job.

The free tier is genuinely usable for light work. If you're testing whether AI in Sheets is worth your time at all, SheetAI costs you nothing to find out.

Coefficient

Coefficient solves a different problem. Instead of processing text inside your spreadsheet, it connects your spreadsheet to external data. Salesforce, HubSpot, MySQL, Snowflake, PostgreSQL, 50+ sources. Live sync, auto-refresh, and two-way writeback.

The AI layer sits on top of the connected data. Ask questions in plain English about your synced datasets and get answers without writing queries. Schedule refreshes so dashboards update automatically. Push changes from Sheets back to your CRM.

If you spend hours every week exporting data from Salesforce into Sheets, cleaning it up, and building reports, Coefficient kills that workflow. The data just lives in Sheets, always current.

Free tier for limited syncs. Pro at $49/month for most useful features. The AI features are secondary to the data connection, which is the real product.

ChatGPT (external)

Sometimes the best AI for Google Sheets isn't in Sheets at all. ChatGPT handles complex formula problems, debugging, and data strategy better than any in-sheet add-on because you can give it more context through conversation.

I paste a broken ARRAYFORMULA into ChatGPT, describe what it should do, and get back a working version with an explanation of what went wrong. I describe a dashboard layout and get the formulas for every cell. I ask for Google Apps Script code and get something that actually runs on the first try most of the time.

The workflow is copy-paste between ChatGPT and Sheets. No live connection, no bulk processing. That makes it impractical for repetitive tasks but unbeatable for one-off problems that the add-ons can't crack.

Free tier available. Plus at $20/month for GPT-5.2 and file uploads (upload a .csv and ask questions about it directly).

Rows AI

Rows is a standalone spreadsheet with AI built into the foundation. Not bolted on, not an add-on. Built in. It comes with 50+ native data connectors (Google Analytics, Stripe, Notion, LinkedIn, databases), an AI analyst that answers questions about your data, and an AI formula builder.

Ask "What were our top 5 products by revenue last quarter?" and Rows pulls the answer from your connected data. Describe a chart and it builds it. The AI-generated dashboards are presentation-ready, which saves the usual export-to-Slides step.

Pro plan at $8/user/month. Team plans available. The free tier covers basic use.

The catch: it's a separate product from Google Sheets. You'd need to migrate workflows, which is a real cost if your team already lives in Sheets. The ecosystem is smaller, with fewer templates and community resources. Some advanced Sheets features (Apps Script, certain functions) don't have equivalents.

Worth trying if you're starting from scratch or if the built-in data connections save you enough time to justify switching.
