PowerPoint add-in
Stop rebuilding slides by hand. Datama embeds the interactive waterfall.
Stop rebuilding variance slides from scratch every close. Configure your budget vs actual or N vs N-1 analysis once in Power BI, Excel or Tableau, then embed your HTML visualizations, for example an interactive Datama waterfall, directly in the presentation your Comex already expects. KPI decomposition, dimensions and segments ranked by impact, mix and volume effects, drill-down included, even in slideshow mode.
Works with your existing data sources and filters. No ETL, no change of tool for presentation day.
HTML Viewer by Datama
Key Features
What the free PowerPoint add-in brings to your deck:
One-click chart embed
Insert any chart generated by Datama (waterfall, KPI tree, variance bridge) directly into a slide.
Universal HTML viewer
Beyond Datama charts, display any HTML file inside PowerPoint, including artifacts generated by AI tools such as Claude, turning your slides into a canvas for any web-based visual.
Presentation-ready rendering
Keep the same clean, audit-friendly visual your stakeholders already see in Tableau, Power BI, Qlik, or Excel.
No more manual rebuilding
Stop taking screenshots or redrawing charts for every deck, reuse the exact analysis you already built.
How it works
From your data to a board-ready slide in three steps
Install HTML viewer by Datama
Add the free Office add-in from PowerPoint: Insert → Add-ins → search for HTML viewer by Datama. IT-friendly, no separate licence for PowerPoint, no gateway to configure.
Build your variance analysis upstream
Prepare Datama Compare in the tool where your numbers live, Power BI, Excel, Tableau, Qlik or Looker Studio. Point at your KPI, comparison dimension and explanation segments: entity, product line, channel, region.
Export HTML and drop it on the slide
Download your visualization as HTML from the source extension, Datama waterfall, Detect, Assess or Explore: then import via file upload or custom code. It appears on the slide, interactive in edit mode and in presentation mode.
Why teams pick it
Built to energize your KPI analysis presentations in PowerPoint
Interactive HTML visualizations, not screenshots
Present any Datama HTML visualization in slideshow mode, waterfall, Detect, Assess or Explore: zoom, split by dimension, read intelligent comments, without leaving PowerPoint or apologizing for a frozen chart.
Budget variance, out of the box
Budget vs actual, forecast vs real or N vs N-1: the market equation splits the move into independent drivers your CFO can follow. A platform of trust for recurring reporting PowerPoint decks.
Key factors, ranked
Interest scoring surfaces the segments that actually explain the gap, entity, channel, product line, country, so you focus the conversation on what matters before the committee asks.
Refresh in minutes each period
Each close, refresh your source data, re-export HTML and update the slide. Same deck structure, new figures, not a full rebuild of charts and labels from a spreadsheet export.
Compare, Detect, Assess & Explore
The free add-in renders every Datama solution you export: gap analysis, anomaly detection, significance tests and granular KPI breakdown, one viewer for your whole reporting toolkit.
Self-contained and meeting-ready
The dataset travels inside the HTML export, so the slide works offline in the room. Datama does not warehouse your figures, important when board packs carry sensitive financial data.
Datama allows us to easily and reliably explain our performance against budget, by displaying only the most significant contributing factors.
