It was first announced at Ignite 2021 and the specification was released in March 2021.[4][5] It is based on spreadsheet-like formulas to make it accessible to large numbers of people.[6] It was also influenced by programming languages and tools like Pascal, Mathematica, and Miranda.[7]

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; if the user changes the content of a cell, the values of all its dependent cells are automatically updated. In a similar fashion, the 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 may connect a component's color property to the value of a slider component; if the user moves the slider, the color changes.[8]

The initial formula language was created by a Microsoft team led by Vijay Mital, Robin Abraham, Shon Katzenberger and Darryl Rubin as part of the Tangram and Siena projects.[8][7] Later, as part of Power Apps, Greg Lindhorst and Mike Stall led the effort to enhance the language to what is now become Power Fx. Power Fx is available as Open-source software.[9] The source code was shared under MIT license by Microsoft on November 2. 2021.[10] Only the documentation was originally open source.[11]
