Power Automate Performance Trick: Replace Apply to Each with XPath
One of the most common Power Automate patterns is using Apply to Each simply to calculate totals, averages, or other summary values.While it works, it often introduces unnecessary actions and makes your flows more complex than they need to be.
In this tutorial, I'll show you a simple performance technique using XPath that can replace many aggregation loops with a single expression. We'll build everything step by step, understand how XPath works, and apply the same pattern to both HTTP API responses and SharePoint Get Items.
In this video you'll learn:
✔️ Why Apply to Each isn't always necessary
✔️ Convert JSON arrays into XML for XPath
✔️ Calculate totals with sum()
✔️ Calculate averages
✔️ Filter data using XPath predicates
✔️ Build dynamic XPath expressions
✔️ Aggregate values by category
✔️ Use XPath with SharePoint Get Items
We'll work through practical examples using:
✔️ HTTP APIs
✔️ SharePoint Lists
✔️ Dynamic category summaries
Important: Whenever your data source can perform the aggregation, let the backend do the work. XPath shines when your flow already contains the data and you need fast, flexible summary calculations.
