AI has landed inside both spreadsheet giants — Gemini in Google Sheets and Copilot in Microsoft Excel. They do broadly the same things (formulas, analysis, summaries from plain English), so the real question isn’t which AI is smarter, but which ecosystem you already work in. Here’s the honest 2026 battle, with real pricing.
Pricing head-to-head
Google Sheets AI (Gemini): via Google AI Pro ~$19.99/month or bundled into Google Workspace business plans. Excel Copilot: via Microsoft 365 Copilot ~$30/user (or $19.99 bundled with M365 Personal). Both add roughly $20–$30/month on top of the base suite.
What each does well
Both generate formulas from plain-English prompts, explain complex sheets, clean data, and summarize. Gemini leans on its huge context and tight Google Workspace integration; Copilot leans on deep Excel feature parity and integration with the rest of Office (Word, Outlook, Teams).
The deciding factor: your ecosystem
The features are close enough that switching suites for the AI rarely makes sense. If your data, files, and team already live in Google Workspace, use Gemini; if in Microsoft 365, use Copilot. Fighting your existing ecosystem costs more than any AI feature gap.
Sheets AI vs Excel Copilot
| Factor | Google Sheets (Gemini) | Excel Copilot |
|---|---|---|
| Price | ~$19.99/mo (Google AI Pro) | ~$30/user (M365 Copilot) |
| Strength | Big context, Workspace | Deep Excel + Office |
| Best for | Google-based teams | Microsoft 365 teams |
| Formula-from-text | Yes | Yes |
A real scenario
A finance analyst weighing the two: their company runs entirely on Microsoft 365, so Excel Copilot ($30) is the obvious pick — it lives in the spreadsheets they already build and pulls into Outlook and Teams for reporting. A startup on Google Workspace would just as clearly choose Gemini in Sheets ($19.99), which is also the cheaper of the two. Neither analyst should switch ecosystems for the AI: the capability gap is small and the migration cost is large. The verdict is refreshingly simple — match the AI to the suite your data already lives in, and let price (Gemini is cheaper) break the tie only if you’re genuinely ecosystem-neutral.
Frequently asked questions
Google Sheets AI or Excel Copilot — which is better?
They’re close in capability — both turn plain English into formulas, analysis, and summaries. The deciding factor is your ecosystem: use Gemini if you’re on Google Workspace, Copilot if you’re on Microsoft 365. Don’t switch suites for the AI.
Which is cheaper?
Google Sheets AI via Google AI Pro (~$19.99/month) is cheaper than Excel Copilot via Microsoft 365 Copilot (~$30/user). But the base suite you already pay for usually decides it more than the AI add-on price.
Should I switch suites to get the better AI?
No — the feature gap is small and migration costs (files, training, integrations) are large. Stick with the suite your team already uses and add its native AI.
