Data Formulator: AI-powered Data Visualization
🪄 Explore data with visualizations, powered by AI agents.
Working with data is hard for two simple reasons:
- Data lives everywhere. Connecting agents to files, databases,
warehouses, and BI tools takes time. It is even harder when agents start
answering before the relationships between data sources are clear.
- Questions evolve as you explore. Each answer can lead to follow-up
questions, comparisons, and new directions. A long chat history makes it
hard to see where you are and how you got there.
Data Formulator provides one visual workspace for exploring and analyzing data:
- Data connectors give agents a common way to connect to different data
sources and maintains a data memory to remember the relationships between them.
- Data Threads let you branch into different questions, compare paths,
and use visualizations to discover deeper insights without losing context.

[!TIP]
Love the charts? They're built on Flint. It's an open-source visualization language that compiles compact chart specs into polished visualizations.
News 🔥🔥🔥
[08-15-2026] Data Formulator 0.8 beta 1 (0.8.0b1) introduces:
- One unified flow: load data, ask questions, review results, and branch in the Data Thread.
- More data sources: use files, local folders, databases, and platforms such as Databricks.
- Better charts: explore more Flint-powered charts, recommendations, themes, and styling tools.
Preview with pip install --pre data_formulator==0.8.0b1 or uvx [email protected].
Install the latest stable release (0.7) with pip install data_formulator or run instantly with uvx data_formulator.
See the changelog for release details.
Previous Updates
Here are milestones that lead to the current design:
- v0.7 (05-28-2026): Turn ANY data into insights in five steps — connect governed data sources, load via agents, explore with the unified
DataAgent + Data Thread, refine 30+ chart types (semantic chart engine powered by Flint) with a style-refinement agent, and share as reports. Plus persistent sessions & workspaces and a multilingual (English/Chinese) UI.
- v0.6 (Demo): Real-time insights from live data — connect to URLs and databases with automatic refresh
- uv support: Faster installation with uv —
uvx data_formulator or uv pip install data_formulator
- v0.5.1 (Demo): Community data loaders, US Map & Pie Chart, editable reports, snappier UI
- v0.5: Vibe with your data, in control — agent mode, data extraction, reports
- v0.2.2 (Demo): Goal-driven exploration with agent recommendations and performance improvements
- v0.2.1.3/4 (Readme | Demo): External data loaders (MySQL, PostgreSQL, MSSQL, Azure Data Explorer, S3, Azure Blob)
- v0.2 (Demos): Large data support with DuckDB integration
- v0.1.7 (Demos): Dataset anchoring for cleaner workflows
- v0.1.6 (Demo): Multi-table support with automatic joins
- Model Support: OpenAI, Azure, Ollama, Anthropic via LiteLLM (feedback)
- Python Package: Easy local installation (try it)
- Visualization Challenges: Test your skills (challenges)
- Data Extraction: Parse data from images and text (demo)
- Initial Release: Blog | Video
Overview
Data Formulator is a Microsoft Research project for data exploration with visualizations powered by AI agents. It combines UI interactions with natural language so analysts can communicate intent, branch into alternative analyses, and share results — starting from any data format (screenshot, text, CSV, or database).
Get Started
Play with Data Formulator with one of the following options.
Desktop downloads
CI builds self-contained Windows and macOS applications for pull requests and
every update to main. Download the latest archives from the Artifacts
section of the most recent
desktop builds workflow.
Workflow artifacts are retained for 30 days. Tagged builds are also attached
as permanent downloads to the corresponding
GitHub Release.
Extract the archive, then launch Data Formulator using the instructions for
your operating system:
- Windows: Run
Data Formulator.exe. If Microsoft Defender SmartScreen
appears, select More info, verify that you downloaded the archive from
this repository, and then select Run anyway.
- macOS: Move
Data Formulator.app to Applications. The first time you
open it, macOS may report that Apple could not verify the app. Open
System Settings → Privacy & Security, scroll to Security, and select
Open Anyway for Data Formulator. Confirm by selecting Open when
prompted.
[!WARNING]
These are automated preview builds and are not currently code-signed or
notarized. Only bypass the operating-system warning when the archive was
downloaded directly from this repository's workflow artifacts or releases.
Option 1: Install via uv (recommended)
uv is an extremely fast Python package manager. If you have uv installed, you can run Data Formulator directly without any setup:
uvx data_formulator
Run uvx data_formulator --help to see all available options, such as custom port, sandboxing mode, and data storage location.
Option 2: Install via pip
Use pip for installation (recommend: install it in a virtual environment).
pip install data_formulator # install
python -m data_formulator # run
Data Formulator will be automatically opened in the browser at http://localhost:5567.
Option 3: Run with Docker
docker compose up --build
Open http://localhost:5567 in your browser. To stop, press Ctrl+C or run docker compose down.
Option 4: Working as developer
You can build Data Formulator locally and develop your own version. Check out details in DEVELOPMENT.md.
Start with the data you already have: upload CSV, TSV, Excel, JSON, screenshots,
or text; connect to databases and data platforms; or ask the analyst to find and
load the data you need. The analyst can discover sources, clarify your request,
propose a loading plan, and let you review the data before adding it to the
workspace.
Continue the conversation in the Data Thread. Ask questions in
natural language and follow the reasoning through explanations, tables, and
editable charts in one history. Refine a result directly, branch from any
earlier step to explore an alternative, or delegate the next investigation to
the analyst. When the analysis is ready, compose the results into a report to
share.
