8 Best AI for Spreadsheets in 2026 (Excel, Sheets, and Beyond)
Spreadsheets quietly became a different tool in 2024. Copilot landed inside Excel, Gemini landed inside Sheets, and a wave of AI-native grids (Rows, Equals, Bricks) showed up acting like Notion crossed with a database. Two years later, the dust has settled. I have a much clearer picture of what actually works versus what was just demo theater.
This post is about two things: the AI that lives inside the spreadsheet you already use, and the AI tools that plug into it. I am skipping the "paste your CSV into ChatGPT" angle because I already wrote about that in ChatGPT for Excel and the best AI for Google Sheets. What follows is the eight I keep coming back to.
Quick comparison
| Tool | Works with | Price | Standout |
|---|---|---|---|
| Microsoft Copilot in Excel | Excel (desktop + web) | $18/user/mo (annual) | Native sidebar, full sheet context |
| Gemini in Google Sheets | Google Sheets | From €9.52/user/mo (Workspace) | "Help me organize" + formula chat |
| Rows | Standalone (web) | Free / $8 per user/mo | AI Analyst built into every grid |
| Equals | Standalone (web) | $1,250/mo | Spreadsheet wired to your CRM + warehouse |
| Formula Bot | Excel + Sheets + web app | $18/mo | Formula generator + dashboards |
| Numerous.ai | Excel + Sheets add-on | $10/user/mo (annual) | AI inside cells via =AI() function |
| Coefficient | Sheets + Excel add-on | Free / $49/mo | AI plus live data connectors |
| SheetAI | Google Sheets add-on | $20/mo | Bring-your-own-key add-on |
Microsoft Copilot in Excel
Microsoft Copilot in Excel is the default for anyone whose job runs on Excel. Open a workbook, hit the Copilot button in the ribbon, and a sidebar opens. You can ask it to summarize a table, build a pivot, draft a formula, highlight outliers, or write a SUMIFS that you would otherwise spend twenty minutes Googling.
The thing that makes Copilot useful versus gimmicky is that it reads the structure of your sheet. It knows which column is a date, which is currency, which is a category. Last week I dropped a 14,000-row transactions table in front of it and said "show me which categories grew month over month and flag any that doubled." It produced a clean pivot plus a column with delta percentages in about ten seconds. The same task in a clean Excel session would have taken me twenty minutes of formula wrangling.
$18/user/month annual, $25.20/user/month monthly. Requires a qualifying Microsoft 365 plan. Bundled options run $22/user/month for Business Standard + Copilot.
Works with: Excel desktop, Excel for the web, Excel mobile. Also Word, PowerPoint, Outlook, Teams.
The catch: $18/user is steep if you only want it for Excel. You are really paying for the whole Microsoft 365 Copilot suite. If your team already has Microsoft 365, it is the easy yes. If you live in Google Sheets, skip it.
Gemini in Google Sheets
Gemini ships inside Google Sheets if you are on Workspace Business Standard or above. The sidebar lives in the top-right corner. "Help me organize" is the entry point I use most: paste raw notes, customer feedback, or a messy CSV, and Gemini proposes a structured table with the columns it thinks you want.
The newer feature I rely on is formula chat. You describe what you want in English ("count distinct emails where signup date is in the last 30 days and source contains 'paid'") and Gemini writes the formula in your active cell. It is not perfect with multi-sheet references, but for single-sheet logic it gets it right around 80% of the time. The other 20% I fix in five seconds.
From €9.52/user/month for Workspace Business Standard (annual, promotional rate; €13.60 standard). Business Plus is €14.77/user/month. Gemini is included from Standard up.
Works with: Google Sheets, Docs, Slides, Gmail, Meet.
The catch: Gemini is conservative. It refuses tasks Copilot would happily attempt, especially anything involving sensitive-looking data. It is also worse than Copilot at heavy pivot logic. But if you live in Google Sheets, it is the obvious default. See how to use AI in Google Sheets for the workflow setup.
Rows
Rows is an AI-native spreadsheet. It looks like a normal grid but every column can pull from a live data source (HubSpot, Stripe, Google Analytics, GitHub, SQL) and an AI Analyst sits in the sidebar ready to answer questions about the data in front of you.
The "AI Analyst" is the feature I keep recommending. Click a chart or a table, ask "why did this dip in March," and it actually traces the data and gives you a plausible answer with the supporting numbers. Numerous wrote me a working ARRAYFORMULA that referenced 3 sheets in 30 seconds; Rows did the same task by just letting me ask in plain English without writing any formula at all. Different philosophy, same result.
Free (5 AI Tasks/month). Plus $8/user/month ($6 annual, 200 AI Tasks). Pro $79/month + $8/user (1,000 AI Tasks). Enterprise custom.
Works with: Standalone web app. Imports from Excel and Google Sheets. Exports to both.
The catch: It is not Excel. You will have to migrate or duplicate workbooks. The free tier's 5 AI Tasks runs out fast. Worth it if your job is dashboards and reports more than financial modeling.
Equals
Equals is what Excel would look like if it were rebuilt in 2024 by ex-Stripe people specifically for finance teams. It is a real spreadsheet, with formulas you would recognize, but it connects directly to your CRM, warehouse, billing system, and ad accounts. No CSV exports. No paste-and-pray.
The AI feature is Analyst. You ask "what is ARR by segment for the last six quarters" and Analyst builds the spreadsheet model from your connected sources. Not a dashboard. A real model with cells you can audit and edit. For SaaS finance leads I work with, this has replaced both their old Excel sheets and their Looker dashboards.
Essential $1,250/month (one connection, 6-hour refresh). Business $2,000/month (one connection, hourly refresh). Extra connectors $199-$699/month.
Works with: Standalone web app. One-way import from Excel/Sheets. CSV export.
The catch: The price is "real company" pricing, not freelancer or solopreneur. Both plans include a Forward Deployed Analyst for setup, which explains the number. If you have a real finance ops budget, this is the answer.
Formula Bot
Formula Bot started in 2022 as a simple "describe a formula, get the formula" generator. It now does dashboards, automation, and AI Actions inside a hosted workspace, but the formula generator is still the most useful piece for me. Type "give me an Excel formula that returns the 3rd word of column A only if column B is greater than 100," and it returns something that actually works.
The dashboards are decent if you want a quick visualization layer over a CSV without setting up a BI tool. I use Formula Bot mainly as a Chrome tab I keep open to translate English into XLOOKUP and INDEX/MATCH when my brain refuses to cooperate.
Starter $18/month (250 messages, 2 dashboards). Max $29/user/month (unlimited messages, shared workspace). Enterprise $149/user/month.
Works with: Excel formulas, Google Sheets formulas, hosted web app with its own grid.
The catch: The free version is limited enough that you will hit the wall in about ten minutes of real use. Worth the $18 if formula generation is your primary need.
Numerous.ai
Numerous.ai is the cleanest "AI in a cell" implementation I have used. Install the add-on for Excel or Google Sheets, then call =AI("classify this review as positive, negative, or neutral", A2) and drag it down 5,000 rows. That is the entire pitch.
I use this all the time for unglamorous batch work: classifying support tickets, extracting company names from messy text, normalizing job titles, translating columns. It is a thousand times faster than running each row through ChatGPT manually. Numerous wrote me a working ARRAYFORMULA that referenced 3 sheets in 30 seconds when I asked it to compare two product catalogs, which is exactly the kind of one-off task I never want to write myself.
Personal/Pro $10/month (billed annually, 500K characters, 500 formula generations). Enterprise $10/user/month, up to 8 users, 1M characters per person. 7-day free trial.
Works with: Excel, Google Sheets (add-on). Same =AI() function works in both.
The catch: The "500K characters" cap goes fast if you are processing long-form text. The Enterprise plan is the one that makes sense for any real production use.
Coefficient
Coefficient sits in a weird and useful position: it is a data connector first (Salesforce, HubSpot, Snowflake, BigQuery, Stripe, Google Ads, all of it) and an AI assistant second. Once your data is in the sheet, the GPT-powered functions (=GPTX(), =GPTSQL(), on-sheet SQL builder) let you write transformations in plain English.
This is the one I recommend to RevOps and analytics teams. Pull a live Salesforce report into Sheets every morning. Use Coefficient's AI to write the SQL that filters and joins it. Push the cleaned table back to Snowflake when you are done. The combination of "live data in" and "AI to wrangle it" is what makes it work.
Free (3 sources, 50 refreshes/month, 10K lifetime OpenAI calls). Starter $49/month. Pro $99/user/month (most popular). Enterprise custom. 17% discount annual.
Works with: Google Sheets and Excel (add-on for both).
The catch: The Free tier is enough to learn the tool but not enough to use it daily. The jump from Starter to Pro is steep. If you are already paying for a BI tool, evaluate whether you need both. See the best AI for data analysis if you are weighing this against a full BI stack.
SheetAI
SheetAI is the Google Sheets add-on for people who want full control. You bring your own API keys from OpenAI, Anthropic, or Replicate, and SheetAI gives you a set of functions (SHEETAI_BRAIN, SHEETAI_LIST, SHEETAI_IMAGE) that you call directly inside cells. The functions are caching-aware, so re-running a sheet does not re-bill you for unchanged inputs.
I keep SheetAI installed because of the bring-your-own-key model. My monthly token bill from Anthropic for SheetAI work is usually under $5, and the $20/month subscription is for the add-on itself. Compared to Numerous, you trade convenience (Numerous handles the keys) for cost control (SheetAI runs on your direct API pricing, which is much cheaper at volume).
Unlimited Monthly $20/month. Unlimited Yearly $200/year. Domain License $299/year (up to 20 users).
Works with: Google Sheets only.
The catch: You have to manage your own API keys, which is fine for technical users and a barrier for everyone else. Sheets-only, so Excel users should look at Numerous instead.
How to choose, by spreadsheet platform
The question is not "which AI is best for spreadsheets" but "which spreadsheet are you in."
You live in Excel: Microsoft Copilot in Excel is the default. Add Numerous.ai for batch =AI() work and Formula Bot for the occasional gnarly formula.
You live in Google Sheets: Gemini is free if you are on Workspace Standard. Add Numerous.ai, SheetAI, or Coefficient depending on whether you need cell-level AI, full BYO-key control, or live data connectors. The full breakdown is in how to use AI in Google Sheets.
You are open to leaving Excel/Sheets: Rows for dashboards and reporting. Equals if you are running real SaaS finance and have a budget.
You are accounting or finance-heavy: Equals for connected modeling, plus see the best AI for accounting for the wider stack.
The setup I actually use is two tools: Copilot or Gemini in whatever spreadsheet I am in, plus Numerous.ai for any task that needs an AI function inside cells. That covers 95% of real work.
FAQ
What is the best AI for spreadsheets in 2026?
Depends on the spreadsheet. Microsoft Copilot in Excel ($18/user/month) for Excel users. Gemini in Google Sheets (from €9.52/user/month with Workspace Standard) for Google Sheets users. Rows ($8/user/month) if you are willing to switch to an AI-native grid.
What is the best free AI for spreadsheets?
Gemini in Google Sheets if you already have a Workspace plan above Starter. Rows has a free tier with 5 AI Tasks per month for an AI-native experience. Formula Bot and Coefficient both have free tiers good enough to learn the tool, but you will hit limits quickly.
Can ChatGPT replace Excel?
No, and it is not trying to. ChatGPT is good at analyzing data you paste into it but it cannot live inside your workbook, refresh data, or run formulas. The tools in this article are built to work alongside or inside Excel and Sheets, which is a different job. For the ChatGPT-specific workflow see ChatGPT for Excel.
Is Copilot worth $18 a month just for Excel?
Only if you are also using Word, PowerPoint, Outlook, and Teams. The $18 is for the whole Microsoft 365 Copilot suite, not just Excel. If you only want AI for Excel, Numerous.ai at $10/user/month covers most use cases for less.
What is the difference between AI-native spreadsheets and AI add-ons?
AI-native spreadsheets (Rows, Equals, Bricks) are built around AI from scratch. The grid, the connectors, the formulas are designed to work with an AI assistant. AI add-ons (Numerous, Formula Bot, SheetAI, Coefficient) plug into Excel or Sheets. Add-ons let you keep your existing workflow. Native sheets force a migration but offer a more integrated experience.
Do I need a separate AI tool if I have Copilot or Gemini?
For most users, no. For specific tasks like running =AI() across thousands of rows, Numerous or SheetAI are better. For live data connectors, Coefficient or Rows are better. The native AI inside Excel and Sheets handles 80% of common tasks; the other 20% is what add-ons exist for.
Is Equals worth $1,250 a month?
For a SaaS finance team replacing both Excel and a BI tool, yes. Each plan includes a Forward Deployed Analyst, hourly or 6-hourly data refresh, and unlimited users. For a solopreneur or freelancer, no. Equals is priced for companies with real revenue ops budgets, not individual users.
Are AI spreadsheets safe with sensitive data?
Microsoft Copilot and Gemini both inherit the data residency and compliance settings of your Microsoft 365 or Google Workspace tenant. SheetAI with your own API keys means data goes directly to your chosen provider (OpenAI, Anthropic). For sensitive financial data, Equals and Coefficient offer enterprise SSO and audit logs. Numerous and Formula Bot are best for non-sensitive workflows.
