Explain
Power Fx is a low-code, Excel-like formula language used across the Power Platform.
In Dynamics 365, it powers logic inside forms, views, business rules, commands, and custom pages.
The ‘private’ context means enterprises maintain full control of the solution, environment, connectors, and security.
Power Fx integrates tightly with Dataverse to express logic without complex coding.
Ideal for business analysts and developers designing scalable business applications.
