Power Automate Function Reference

Power Automate expressions are where a lot of the real magic happens, and this is my reference for the functions that power them. When the point-and-click designer runs out of road, a well-placed expression gets you exactly what you need. I document the everyday date and time helpers like the "addDays" function, the "addHours" function, and the "addMinutes" function, along with the more flexible "addToTime" function for shifting timestamps. I cover math with the "add" function, logic with the "and" function, and data shaping with the "addProperty" function and the "array" function. Need to convert data types? The "base64ToBinary" function gets its own walkthrough, and the "action" and "actions" functions let you reach into earlier steps. Every entry gives you the syntax, the parameters, the return value, a practical example, and the edge cases that catch people out.
