Power Fx is the low-code formula language of the Power Platform. If you can write Excel formulas, you can build Power Apps logic — the same dialect, the same syntax. Power Fx runs in Canvas apps, Power Pages, Dataverse columns, and Power Automate.
What matters for Theia: your business teams can make small adjustments themselves, without calling in developers every time. That reduces time-to-change and takes pressure off IT.
