Microsoft Data Formulator: Create Stunning Data Visualizations with AI
In today’s data-driven world, transforming raw information into actionable insights is critical. However, crafting compelling visualizations often requires time-consuming data manipulation and coding expertise. Enter Microsoft Data Formulator, an AI-powered tool designed to revolutionize how analysts and developers create rich, interactive visualizations.
This guide dives deep into Data Formulator’s capabilities, setup process, and unique features, empowering you to harness AI for seamless data storytelling.
What is Microsoft Data Formulator?
Microsoft Data Formulator is an open-source application developed by Microsoft Research that bridges the gap between raw data and insightful visualizations using artificial intelligence. Unlike traditional tools that rely on manual coding or rigid templates, Data Formulator combines natural language prompts and drag-and-drop interactions to simplify complex data transformations.
Key Features:
- AI-Powered Data Transformation: Automatically generate new fields or metrics using natural language.
- Multi-Dataset Support: Merge and analyze data from multiple sources effortlessly.
- Flexible Model Integration: Works with OpenAI, Azure, Anthropic, and Ollama models.
- Iterative Visualization: Refine charts through follow-up prompts and UI adjustments.
- Code Transparency: Inspect and modify the Python code behind every visualization.

How to Use Data Formulator: A Step-by-Step Guide
Step 1: Load Your Data
Start by uploading a CSV or connecting to a database. Data Formulator supports common formats and even messy text/image inputs.
Step 2: Design Your Visualization
- Drag-and-Drop Fields: Assign columns to X/Y axes, color, or size.
- Natural Language Prompts: Type commands like “Show sales trends by region” or “Compare quarterly revenue.”
Step 3: Formulate New Metrics
Need a calculated field? Enter a name (e.g., “Profit Margin”) and describe it in plain language. Click Formulate to let AI generate the code.
Step 4: Iterate and Refine
Adjust encodings or type follow-up prompts (e.g., “Highlight top 5 products”). Track changes in the Data Threads panel.
Step 5: Export and Share
Download charts as images or export the underlying code for further customization.
Why Choose Data Formulator Over Traditional Tools?
1. Blending UI and Natural Language
Most AI tools force users to describe everything in text. Data Formulator’s hybrid approach allows precise control via drag-and-drop, while offloading complex transformations to AI.
2. Transparency and Control
Every visualization comes with generated Python code, making it easy to audit or modify logic.
3. Community-Driven Innovation
With challenges, open-source contributions, and model feedback loops, Data Formulator evolves with user input.
4. Enterprise-Grade Security
API keys are stored locally, and Microsoft’s Code of Conduct ensures ethical usage.
Real-World Applications
Case Study: Renewable Energy Analysis
A user uploaded a dataset on global renewable energy production. By asking, “Show the top 5 countries by solar capacity,” Data Formulator:
- Calculated total capacity per nation.
- Ranked results.
- Generated an interactive bar chart.
Follow-up prompts like “Convert to percentage of total” triggered instant recalculations.
Behind the Scenes: The Research Powering Data Formulator
Data Formulator builds on peer-reviewed research, including:
- Data Formulator 2: Iteratively Creating Visualizations with AI (arXiv:2408.16119)
- Concept-Driven Visualization Authoring (arXiv:2309.10094)
These papers highlight how blending UI actions with NL prompts reduces cognitive load while maintaining user intent.
