Function Day
Function Day is where I explore the basics of a function and share recommendations on how to actually use it. I focus on Power Automate, SharePoint, and Power Apps, because there is so much to dig into there, though other references show up from time to time. Do not expect an exhaustive list of every function, since Microsoft's own reference already covers that. Instead I pick the common ones and build from there, one function at a time. Articles land on a regular schedule, and with three platforms to rotate through you can count on Power Automate, SharePoint, and Power Apps entries coming around in turn. When time allows I speed things up, but a steady rhythm is what keeps Function Day delivering useful, in-depth breakdowns you can rely on.

Checks if a string is an integer.

Power Apps: LookUp Function
Returns the first record that matches a condition, or a single reduced value. Blank if nothing matches.
