AI Excel analysis that runs real maths, not predictions.
AI Excel analysis only earns its name when the AI does the analysis rather than narrating one. DataHub Pro reads your .xlsx — sheets, named ranges, formulas, dates, even messy headers — and runs deterministic pandas operations to produce KPIs, anomaly flags, RFM segments, Holt-Winters forecasts and a branded Word/PowerPoint report. Every number is traced back to the operations that produced it, so the audit trail is shorter than your usual review.

Why Excel + ChatGPT is a fragile workflow
Excel is the most-used analytics tool on Earth. ChatGPT is the most-used AI tool on Earth. Pasting one into the other should be the productivity revolution of the decade — but in practice the workflow breaks in three predictable places.
1. The model never sees the whole sheet
Free-tier ChatGPT can only ingest about 8,000 tokens of CSV — roughly 800 rows of mid-sized data. Past that, you're either summarising before you start (defeating the point) or relying on the Code Interpreter / Advanced Data Analysis mode, which then runs Python but with no audit trail and a session that times out.
2. Excel-specific gotchas confuse it
Merged cells, multiple sheets in one file, dates stored as serial numbers, percentages stored as decimals, formulas referring across sheets — every one of these breaks naive AI parsing. The model often quietly mis-interprets and gives a confident wrong answer.
3. The output isn't actionable
You wanted a report. The chat window gives you prose. Now you copy the prose into Word, format it, redo the charts in Excel, paste the charts back in, write the executive summary yourself. The AI saved you minutes of analysis and gave them back as minutes of formatting.
How DataHub Pro analyses Excel files
A purpose-built Excel parser, a tool-use AI on top, and one-click report export at the end. No copy-paste required.
Sheet-aware Excel parsing
Multi-sheet workbooks open with a sheet picker. Merged cells, header detection, date serial numbers, percentage formats and formulas are handled. Files with junk above the header row are auto-cleaned (or cleaned with one prompt).
Tool-use AI for arithmetic
Ask Your Data takes natural-language questions and translates them into pandas operations. Every answer comes with the call trace and the row count used, so a partial answer is never silently returned as a complete one.
AutoInsights at upload
Within seconds of upload, the platform identifies revenue / count / time columns, computes 4-8 KPIs, writes 3 narrative insights and flags any data-quality concerns. You don't pick the analyses — the platform picks the right ones for your file.
Forecasting + anomalies + cohorts
Time-series columns are auto-forecast with Holt-Winters and confidence bands. Numeric columns are scanned for anomalies. Customer-and-date columns trigger cohort analysis. RFM scoring runs on transaction-shaped files.
Pivot tables, drag-and-drop
Build pivots in a UI rather than the Excel ribbon. Subtotals are auto-added; the pivot can be exported back as .xlsx, pinned to a dashboard, or fed into Auto Report.
DOCX, PPTX and XLSX export
Hit Export and the platform generates a fully editable Word document, PowerPoint deck, and XLSX summary. White-labelled with your logo on Pro. Open in Office or Google Docs and edit normally.
Workflows that take 20 minutes instead of 4 hours
The biggest wins come from work that used to be repetitive: the same Excel-then-Word workflow you do every week or month. Recurring deliverables collapse from half-day jobs to coffee-break jobs.
- Monthly variance pack. Drop in actuals vs budget; get period-comparison charts, top-five variances with written explanations, anomaly callouts.
- Weekly client KPI report. Drop in client metrics; get a branded Word doc with executive summary and editable charts.
- Quarterly board pack. Drop in finance + ops + sales spreadsheets; get a unified PPTX with sections for each function.
- Customer health review. Drop in transaction or usage data; get RFM scoring, churn-risk flags, top-50 at-risk accounts.
- Margin analysis. Drop in product-level revenue and cost; get margin-by-product, outliers, and a what-if calculator.
Each of these uses the same primitives — KPIs, AutoInsights, charts, Auto Report. Once your team learns the upload-and-export rhythm, every new spreadsheet workflow takes minutes to set up.
Who benefits most from AI Excel analysis
Finance teams at SMEs and growth-stage businesses
If month-end takes a week and most of it is moving numbers between Excel and Word, this is built for you. The Pro tier pays for itself if it saves a single half-day a month.
Insight agencies, consultancies and accountants
Every client deliverable that starts "they sent us a spreadsheet" — performance reports, audit packs, advisory deliverables — fits the workflow. White-label output with the client's logo to ship faster without lowering the bar.
Operations and revenue analysts
Anyone who exports CSVs from Salesforce, HubSpot, Stripe, Shopify, Xero or QuickBooks for ad-hoc analysis. Drop the export in, get the analysis without writing the formulas.
Less of a fit if your "Excel" is really a 5GB warehouse extract or your reporting is real-time live dashboards from a transactional database. Those workloads belong to a warehouse-connected BI tool.
When AI Excel analysis isn't the right fit
If your data is locked in a multi-sheet financial model with deeply linked formulas where the model is the deliverable (think LBO models, real-options pricing), DataHub Pro is the wrong shape — those workbooks belong in Excel itself. The platform is best when the spreadsheet is the input and a report or dashboard is the output, not when the spreadsheet is both.
FAQs
Does DataHub Pro open .xlsx files with multiple sheets?
Yes. On upload, you pick which sheet to analyse from a sheet picker (or analyse them in turn). Merged cells, header rows that aren't on row 1, formula values, percentage and currency formats and date serial numbers are handled.
Can I keep my data in the UK/EU?
Yes — UK/EU data residency is the default. Files are stored in UK/EU regions and AI requests run through a UK/EU-hosted LLM endpoint where available, falling back to EU-region OpenAI/Anthropic regions when not. A signed DPA is available on the GDPR page.
How does this compare to Excel's built-in Copilot?
Excel's Copilot is good for in-cell actions (summarise, generate formulas, format) and improves quickly. It's optimised for editing the spreadsheet you're in. DataHub Pro is optimised for the next step: turning the spreadsheet into a dashboard, an insight summary, and a Word/PowerPoint report. They're complementary tools — Copilot inside Excel, DataHub Pro for the workflow that ends in a deliverable.
What's the file-size limit?
Free tier: 50 MB and 100,000 rows. Pro tier: 200 MB and 2,000,000 rows. For most agencies and SME finance teams a typical Excel file is under 10 MB.
Are my Excel files used to train AI models?
No. We don't train models on customer data, and our LLM providers don't either when called via the API in business mode. Files are encrypted at rest, deleted on request, and excluded from any model-training pipeline.
Can DataHub Pro generate Excel reports as well as Word?
Yes — XLSX export ships an Excel summary with KPIs, the AutoInsights summary, the comparison tables and any pivot tables you've built. Auto Report generates DOCX and PPTX. Many users export both: the XLSX is the working file, the DOCX is the deliverable.
Will it cope with messy spreadsheets — merged cells, junk rows above the header, dates in random formats?
Yes. The Excel parser auto-detects header rows, ignores leading junk, identifies date columns including UK day-first formats, coerces strings-that-are-actually-numbers, and handles merged cells by carrying forward values. If the file is too messy to auto-clean, AI Cleanse takes a single prompt (e.g. "header is on row 4, drop columns A and B") and applies it.
Can I share results with colleagues who don't have an account?
Yes. Dashboards have public-share links (with optional password protection). Auto Report DOCX/PPTX/XLSX exports are downloadable files — share by email, Slack, or upload to wherever your team works. No login required to read them.
Does the AI explain its reasoning?
Yes — every AI answer ships with the tool calls that produced it: the column it read, the filters applied, the aggregation used. You can click through to see the underlying numbers. For narrative insights, the platform shows the period and the data points the insight is based on.
How does AI Excel analysis interact with our existing BI tools?
It complements them. Many teams use Power BI / Tableau / Looker for live dashboards and DataHub Pro for spreadsheet-driven analysis and report writing. The output of DataHub Pro (Word docs, PowerPoint decks, Excel summaries) drops into existing review processes without changing tools downstream.
Try AI Excel analysis on your own .xlsx.
Drop in any Excel file. The free tier handles up to 50 MB and 100,000 rows — more than enough for a real test on your monthly close pack or a recent client report.
