TL;DR

Formula generation only: Ajelix, Formula Bot, GPT Excel, Numerous AI — cheap or free, narrow scope.

Inside Microsoft Excel: Copilot for Microsoft 365 (£24.70/user/mo on top of Microsoft 365).

Enterprise BI with AI layered on: Tableau, Power BI, Domo, Polymer, KNIME — £600+ per seat or seat-bundled.

How I evaluated these tools

Three things matter for AI-and-Excel: (1) does it work on a real spreadsheet without restructuring it, (2) is the math auditable (does it show its working, or just give you a number), and (3) is the price honest for a small or mid-sized team. Tools that fail on auditability are dangerous — an AI that hallucinates a wrong total looks identical to one that gets it right. I weighted that heavily.

2.Ajelix

From $9/mo

Browser-based assistant that generates Excel formulas, VBA macros and SQL queries from natural language. Add-ins for Excel and Google Sheets. Strongest in the formula-generation niche.

Best atFormula generation in plain English; explanation of existing formulas you've inherited.
Worst atWhole-spreadsheet analysis or dashboarding — not the goal. No exports beyond the formula itself.

3.Formula Bot

Free + paid tiers

Popular text-to-formula tool with both web and Excel/Sheets add-in. Adds chart generation and "ask your sheet" features on higher tiers. The brand most people land on first when they search for Excel AI.

Best atQuick formulas, free tier for one-off jobs, simple charts.
Worst atAuditability — the chat-based "ask your sheet" output isn't accompanied by the operations it ran.
Visit Formula Bot →

4.GPT Excel

Free + paid

UK-built (gptexcel.uk) AI formula and macro generator with VBA, regex, SQL outputs. Lightweight, focused, fast. Often pops up in Google's "AI tools for Excel data analysis" entity panel.

Best atFormula generation, regex generation, light VBA scripts.
Worst atSame as the formula-niche category — not designed for multi-step analysis or reporting.

5.Microsoft Copilot for Excel

£24.70/user/mo (M365 add-on)

Native AI assistant inside Excel. Suggests formulas, generates summaries, adds conditional formatting, surfaces patterns in selected ranges. Requires a Microsoft 365 Business Standard or higher subscription.

Best atAnyone already in Microsoft 365 who wants AI inside the Excel grid itself, not in a separate tab.
Worst atCross-file analysis, custom dashboards, exports to anything other than Excel/Word/PPT. Locked to Microsoft 365.

6.Numerous AI

From $10/mo

An "=AI()" function for Excel and Google Sheets. Drop a formula in a cell, get a generative answer per row — categorisation, sentiment, classification at scale. Niche, but the niche is genuinely useful.

Best atBulk classification or extraction across thousands of rows where each cell needs an LLM call.
Worst atAnything that isn't per-row generation — not a dashboarding or analysis tool.

7.ChatGPT (Advanced Data Analysis)

$20/mo (Plus)

Upload a spreadsheet, ChatGPT runs Python in a sandbox to compute answers and produce charts. Powerful, general-purpose. The original "ask your file" tool.

Best atOpen-ended exploratory analysis where you don't know what question you'll ask next.
Worst atRepeatable workflows and team collaboration — each conversation is ephemeral. No dashboards, no scheduled reports, no multi-user state.

8.Polymer

From $25/mo

Turns Google Sheets, CSVs, or BigQuery tables into auto-generated business intelligence dashboards. Strong AutoExplorer feature that suggests interesting cuts of the data.

Best atQuick-look dashboards from cloud-stored data with minimal setup.
Worst atSpreadsheet-native workflows where the data lives locally; offline analysis.
Visit Polymer →

9.Tableau

From $75/user/mo

The industry-standard enterprise BI platform. Tableau Pulse and Einstein Discovery layer GenAI insights on top. Beautiful, deep, expensive.

Best atLarge organisations with central data teams; pixel-perfect interactive dashboards.
Worst atSmall teams without a data engineer. Cost. Time-to-first-insight is days, not minutes.

10.Microsoft Power BI

From £8.20/user/mo (Pro)

Microsoft's enterprise BI offering, with Copilot as the AI layer. Deeply integrated with the rest of the Microsoft 365 stack.

Best atMicrosoft-shop organisations; complex semantic models; DAX-driven reporting.
Worst atSteep learning curve for non-technical users. Cross-platform fit is weaker outside Microsoft.

11.Domo

Custom pricing

Cloud-native BI platform with AI-driven storytelling and 1000+ data connectors. Targeted at large organisations with many data sources.

Best atMulti-source data consolidation at enterprise scale.

12.KNIME

Free (open source) + paid server

Open-source visual data science platform. Drag-and-drop workflow nodes for data prep, ML, and increasingly GenAI. Genuinely powerful for those willing to learn the paradigm.

Best atReproducible data-science pipelines; teams with technical analysts; free for individual use.
Worst atTime-to-first-result for non-technical users; not a spreadsheet-native tool.

Frequently asked questions

What's the best AI tool for Excel data analysis in 2026?
It depends on the use case. For pure formula generation: Ajelix or Formula Bot. For end-to-end analysis with auditable AI: DataHub Pro at from $14.99/mo. For one-off exploration: ChatGPT Advanced Data Analysis at $20/month. For enterprise BI with AI overlays: Tableau, Power BI or Domo (£600+/seat). The full landscape is in the comparison.
Which AI tool for Excel doesn't hallucinate?
Tools that use 'tool-use' (the AI writes deterministic code that runs on the data, returning both answer and call trace) avoid hallucinations on numerical operations. DataHub Pro and ChatGPT Advanced Data Analysis both work this way. Tools that have the LLM 'eyeball' the spreadsheet and produce free-form output are more prone to hallucination.
What's a UK-built AI tool for Excel?
DataHub Pro (datahubpro.co.uk, London) and GPT Excel (gptexcel.uk) are the UK-built options. DataHub Pro is broader (full analytics platform); GPT Excel is narrower (formula generation only).
Is Microsoft Copilot for Excel worth it?
If you're already paying for Microsoft 365 Business Standard or higher, the £24.70/user/month Copilot add-on is convenient — AI is inside the Excel grid itself. For analysis workflows that go beyond a single Excel file (cross-file, dashboards, scheduled reports), a purpose-built tool wins.
What's the cheapest AI tool for Excel?
Genuinely free: GPT Excel (formula generation), Formula Bot (free tier), our own free forecasting, anomaly, and cohort tools. Cheapest paid: Ajelix from $9/month or DataHub Pro at from $14.99/mo for full analytics.
