How to Convert Excel to PowerPoint Slides with Nano Banana (Step-by-Step Guide)
Franklin·
On February 26, 2026, Google fundamentally altered the landscape of data visualization by officially launching Nano Banana 2, powered by the robust Gemini 3.1 Flash image and multimodal model. For years, business professionals have struggled with the tedious, time-consuming process of manually turning rows of boring Excel data into visually compelling, boardroom-ready presentations.
This guide will show you exactly what AI Excel analysis is, what it means to convert Excel to PowerPoint slides automatically, and the critical differences between the Nano Banana 2 and Nano Banana Pro models. More importantly, we will outline an automated, end-to-end workflow utilizing these AI tools to exponentially accelerate your data analysis and slide-deck creation. Before diving into the deep data workflows, if you are looking to generate presentations from more generalized documents, I highly recommend checking out our foundational guide to Create PPT Slides from Any Topic or File with AI.
Ultimately, the goal is seamless integration: transforming raw Excel data analysis directly into automated PPT visual presentations with zero friction.
Converting Excel to PowerPoint slides using AI is the fully automated process of utilizing artificial intelligence to read raw spreadsheet data, clean the dataset, extract core actionable business insights, and map those findings directly into professional, visually striking slide layouts.
Unlike traditional "copy and paste" methods or basic macro integrations, modern AI presentation workflows do not just move numbers from a cell to a text box. They act as a virtual data scientist and designer. The AI comprehensively understands the context of the metrics, chooses the optimal chart types (e.g., converting sales trends into line graphs or market share into pie charts), and generates a structured, narrative-driven presentation ready for immediate business use.
Understanding the distinction between Google’s latest multimodal releases is crucial for optimizing your workflow.
Nano Banana 2 (Powered by Gemini 3.1 Flash): This is the lightning-fast, lightweight iteration designed for speed. It excels at rapid, basic chart generation and handling simple, straightforward datasets. It is the go-to model when you need a quick visual representation of a clean table in seconds.
Nano Banana Pro: This is the flagship, enterprise-grade multimodal model. It possesses unparalleled data reasoning capabilities, complex logic processing, and advanced layout generation. It can interpret messy datasets, cross-reference multiple data sheets, and construct highly sophisticated slide aesthetics.
Who Should Use Which? If you need a quick draft or a single basic chart, choose Nano Banana 2. If you are preparing a serious commercial data report, conducting deep AI Excel analysis, or need boardroom-level slide layouts, Nano Banana Pro is the definitive choice.
When it comes to high-stakes data-driven presentations, Nano Banana Pro offers five distinct advantages over traditional software:
It doesn't just read headers; it understands complex correlations within massive datasets, identifying anomalies, trends, and KPIs that a human might miss.
It autonomously designs high-end aesthetic layouts, ensuring the spatial arrangement of text, charts, and negative space aligns with top-tier consulting firm standards.
The model intelligently selects the exact chart format (waterfall, scatter plot, dynamic bar) that best visualizes the specific data intent with zero distortion.
Instead of just dumping data on a slide, it structures the deck with a logical flow—executive summary, supporting metrics, and actionable conclusions.
It generates output in widely adopted, native presentation formats, allowing for immediate download and minor human tweaking if necessary.
Model | Best For | Key Advantage | Key Limitation | Speed | Text Accuracy |
Nano Banana 2 | Quick drafts, single charts, simple datasets | Extreme processing speed and low latency | Struggles with highly complex, multi-layered data reasoning | Ultra-Fast | High |
Nano Banana Pro | End-to-end commercial reports, complex analysis | Deep data reasoning and premium layout aesthetics | Slower generation time compared to the Flash variant | Moderate | Supreme |
Nano Banana is being integrated across various AI ecosystems, but platform capabilities vary wildly.
