powerfx
Power Fx python bridge to invoke c# implementation.
Decision gist · record as of 2026-08-14
Yes-with-conditions. The package has no known vulnerabilities and permissive licensing. However, it is in early release (0.0.34), aging (235 days since last update), and lacks visible repository metadata, making its maintenance status unclear. Install only if you specifically need Power Fx evaluation in Python and can tolerate potential instability or lack of future updates. Verify that pythonnet works reliably on your target platform before committing to it.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later and .NET runtime (via pythonnet dependency); cffi also requires a C compiler on some platforms.
- Low install friction with a pure-wheel distribution, but the package is aging (235 days since last release) and depends on pythonnet, which requires .NET runtime availability on the system.
- Maintenance signal is unclear due to missing repository metadata.

What it is and what it does
powerfx is a Python wrapper that bridges to a C# implementation of Power Fx, Microsoft's formula language used in Power Apps and Power Automate. It lets you evaluate Power Fx expressions from Python code by delegating to the underlying .NET runtime through pythonnet and cffi.
The package is a thin interop layer: you install it, import it, and call Power Fx formulas as if they were Python functions. It requires Python 3.10 or later and depends on pythonnet to communicate with the C# side, plus cffi for low-level C interoperability. The package is in early release (version 0.0.34) and has not been updated in 235 days, so stability and feature completeness are not yet established.
Use it for
- Evaluate Power Fx formulas in Python scripts without requiring Power Apps or Power Automate runtime.
- Migrate Power Fx logic from Microsoft platforms into Python-based data pipelines or ETL workflows.
- Test Power Fx expressions programmatically as part of a Python test suite.
- Prototype Power Fx formulas in Python before deploying them to Power Apps.
- Integrate Power Fx formula evaluation into Python applications that need Microsoft expression semantics.
