Why these?
Project tracking, KPI dashboards, budgets, forecasting, RFM and cohort retention — the analyses that every team running on spreadsheets needs at some point and almost no one builds well. Most spreadsheet users either skip them entirely (and fly blind) or pay for a tool that returns the same answer with less control.
The templates give you the maths, transparently. The full DataHub Pro platform gives you the same maths on every spreadsheet you ever upload, plus 47 other analyses, plus branded DOCX/PPTX exports, plus auditable AI Q&A — for from $14.99/mo.
Compatibility
Files are standard .xlsx format. Tested and validated in:
- Microsoft Excel (2016 and later, Windows + Mac)
- Google Sheets (upload via File → Import → Replace spreadsheet)
- LibreOffice Calc (which is how all 4,772 formulas were independently verified)
- Apple Numbers (charts may render differently, formulas calculate correctly)
Licensing
Free for any use — personal, commercial, modification, redistribution. No attribution required (but appreciated). If you find them useful, share the link to this page rather than re-uploading the files; that way readers can always find the latest version.
