Microsoft Power Fx is a free and open source low-code, general-purpose programming language for expressing logic across the Microsoft Power Platform.[1][2]

The programming language was first announced at Ignite 2021 and the specification was released in March 2021.[3][4] It is based on spreadsheet-like formulas to make it accessible to a large number of people.[5] Power Fx was also influenced by programming languages and tools like Pascal, Mathematica, and Miranda.[6]

As Microsoft describes the language, it heavily borrows from the spreadsheet paradigm. In a spreadsheet, cells can contain formulas referring to the contents of other cells, and if the user changes the content of a cell, the values of all dependent cells are automatically updated. In a similar fashion, the various properties of components in a Power Fx program are connected by formulas (whose syntax is very reminiscent of Excel) and their values are automatically updated if changes occur. For instance, a simple formula might connect the color property of some component to the value of a slider component, and if the user moves the slider, the color will automatically change.[7]

The Power Fx language was developed by a team at Microsoft led by Vijay Mital, Robin Abraham, Shon Katzenberger and Darryl Rubin.[7][6] Power Fx is available as Open-source software.[8] The source code was shared under MIT license by Microsoft on November 2. 2021.[9] The documentation only was open source earlier.
