AI in Spreadsheets Has Changed. A Lot.
Two years ago, "AI in spreadsheets" meant pasting ChatGPT output into cells by hand. Now there are add-ons that let you classify, generate, extract, and tag data with a single formula — dragged across thousands of rows.
The catch? Not all of them are worth your time. Some charge $50/month for what you could do with a free tool and your own API key. Others look slick but fall apart on batch jobs.
I tested the five most popular options on real tasks — classifying customer reviews, writing ad copy, extracting structured data from messy text — and here's how they stack up.
The Quick Comparison
| Tool | Platform | AI Models | Free Tier | Custom Functions | Multi-Provider | Pricing |
|---|---|---|---|---|---|---|
| SheetAI | Google Sheets | GPT-4o, Claude, Gemini, Grok | Yes | 8+ functions | Yes | Free + BYOK (no markup) |
| Numerous.ai | Google Sheets, Excel | GPT-4o | Limited | 3 functions | No | From $19/mo |
| Coefficient | Google Sheets, Excel | GPT-4 | Limited | 2 functions | No | From $49/mo |
| GPT for Sheets | Google Sheets | GPT-4, GPT-4o | No | 5+ functions | No | Free + OpenAI API costs |
| Rows.com | Own platform | Built-in AI | Yes | Native | N/A | From $29/mo |
1. SheetAI — Best Overall
SheetAI is a Google Sheets add-on that gives you AI-powered functions across multiple providers — OpenAI, Anthropic, Google, and xAI — from one interface. You write a formula once and can switch the underlying model without touching your spreadsheet.
That flexibility alone puts it ahead, but the function library is what really separates it. Instead of forcing you to prompt-engineer everything through a generic =AI() call, SheetAI gives you purpose-built functions for the most common tasks.
See It in Action
Here's what classifying customer sentiment actually looks like:
=SHEETAI_CLASSIFY(A2, "Positive, Negative, Neutral")Input (A2)
The product arrived damaged and customer service took 3 days to respond. Very disappointed.
AI Output
Negative
Need to pull structured fields out of messy text? One formula:
=SHEETAI_EXTRACT(A2, "product_name, issue_type, sentiment")Input (A2)
My AirPods Pro case cracked after 2 weeks. Want a refund.
AI Output
{"product_name": "AirPods Pro", "issue_type": "Defective product", "sentiment": "Negative"}
And for general content generation — ad copy, descriptions, summaries:
=SHEETAI("Write a 1-sentence Google Ad for: " & A2)Input (A2)
Ergonomic standing desk with memory presets
AI Output
Upgrade your workspace with a standing desk that remembers your perfect height.
=SHEETAI_TAG(A2, "Quality, Shipping, Price, Service, Packaging")Input (A2)
Shipping was fast but the box was crushed. Product itself looks fine though.
AI Output
Shipping, Packaging
I dragged these across 500 rows. Processing took about 8 minutes. Spot-checking 50 rows, I found maybe 3 I'd have labeled differently — solid accuracy for bulk work.

2. Numerous.ai — Best for Simple Tasks
Numerous is a clean, no-frills add-on for Google Sheets and Excel. Their main function is =AI(), and it handles basic text generation well.
=AI("Summarize in 10 words: " & A2)Input (A2)
The product quality is amazing but delivery took over two weeks and the packaging was damaged when it arrived.
AI Output
Great product quality, slow delivery, damaged packaging upon arrival.
It works. But compare what happens when you need to classify data:
Formula
=SHEETAI_CLASSIFY(A2, "Bug, Feature, Billing")Result
Bug
Formula
=AI("Classify into Bug, Feature, or Billing: " & A2)Result
This appears to be a Bug report.
SheetAI returns a clean label. Numerous returns a sentence you'll need to clean up before you can filter or pivot on it. Multiply that cleanup across 500 rows and you've got a problem.
Google Sheets + Excel
Works in both platforms
Simple Interface
Easy to learn, minimal setup
Multi-Provider AI
OpenAI only — no Claude, Gemini, or Grok
Specialized Functions
No dedicated CLASSIFY, EXTRACT, or TAG
Bring Your Own Key
Subscription pricing only
Context / Brain
No way to feed custom context
Numerous is fine if all you need is occasional text generation. But for any structured data work — classification, extraction, tagging — you're fighting the tool instead of using it.
3. Coefficient — Best for Data Imports
Coefficient is primarily a data connector that pulls live data from Salesforce, HubSpot, and databases into your spreadsheet. The AI features are a side dish, not the main course.
=COEFFICIENT_GPT("Categorize this lead: " & A2)Input (A2)
Enterprise company, 500+ employees, evaluated 3 competitors, ready to buy
AI Output
Hot Lead - Enterprise
It can do basic GPT-powered analysis, but compare the depth:
Formula
=SHEETAI_EXTRACT(A2, "company_size, intent, segment")Result
{"company_size": "Enterprise", "intent": "High", "segment": "Ready to buy"}
Formula
=COEFFICIENT_GPT("Extract company size, intent, and segment: " & A2)Result
Enterprise company with high purchase intent
SheetAI gives you structured JSON you can parse. Coefficient gives you prose.
Live Data Connectors
Pull from Salesforce, HubSpot, databases in real-time
Google Sheets + Excel
Works in both platforms
Dedicated AI Functions
Basic GPT only — no classification or extraction functions
Multi-Provider AI

Bring Your Own Key

Affordable Entry

4. GPT for Sheets — Best Budget Option
GPT for Sheets is one of the OGs. Free add-on, bring your own OpenAI key, decent function library. It's been around long enough to have solid documentation and community support.
=GPT_CLASSIFY(A2, "Urgent, Normal, Low")Input (A2)
Our entire billing system is down and customers can't make payments
AI Output
Urgent
The function library is respectable — GPT(), GPT_LIST(), GPT_TABLE(), GPT_FILL(), GPT_CLASSIFY(). But the lack of a context feature hurts:
Formula
=SHEETAI_BRAIN("Classify this ticket", A2)Result
Uses your custom knowledge base for accurate, domain-specific results
Formula
=GPT("Classify this ticket: " & A2 & " Context: " & B2 & C2 & D2)Result
Manual concatenation of context — messy and brittle
SheetAI's BRAIN function lets you attach a knowledge base. With GPT for Sheets, you're manually stuffing context into prompts with string concatenation. It works on 10 rows. It breaks on 500.
No Subscription Fee
Free add-on — just pay OpenAI API costs
Good Documentation
Years of community guides and examples
Dedicated CLASSIFY
Has GPT_CLASSIFY for structured output
Multi-Provider AI
OpenAI only
Context / Brain
No built-in context feature
Reliable Batch Processing
Gets sluggish on large jobs, unhelpful error messages
5. Rows.com — Best Standalone Platform
Rows isn't an add-on — it's a completely separate spreadsheet with AI built into the foundation. The integration feels tighter because it is tighter. AI isn't bolted on; it's part of the product.
=SUMMARIZE(A2)Input (A2)
Q1 sales report showing 23% growth in APAC region driven by enterprise accounts while EMEA declined 5% due to currency headwinds...
AI Output
Q1: APAC grew 23% (enterprise-led), EMEA declined 5% (currency impact).
Clean. But there's a big trade-off:
Formula
Works inside Google SheetsResult
Your team already knows it. Sharing, permissions, integrations — all work.
Formula
Separate platform entirelyResult
New tool to learn. No Google Workspace integration. Team adoption friction.
Native AI Integration
AI feels built-in, not added on
Built-in Data Connectors
API imports and web scraping included
Modern Interface
Clean, contemporary design
Google Sheets Compatible
Completely separate platform — no Sheets integration
Team Adoption
Everyone needs to learn a new tool
Existing Ecosystem
Can't use your current Google Workspace integrations
Rows is impressive technology. But for most teams that already live in Google Workspace, switching platforms is a dealbreaker.
