Power Automate array variable apply to each

Here we will see how to loop the array using applying it to each item in an array in the Power Automate.

So here we will create a list of arrays in power automate and then add apply to each control action to loop through the array. At last, store the list of items from an array to the SharePoint list.

So here I have created a Technology list in SharePoint having one column where we will store the Technology name. like below:

Next in Power Automate, create a Manually triggered Flow. Then click on the Next step.

Select the Initialize variable, and set the variable name, type as an array, and set the value like the below array.

Now we will loop through each item in an array using Apply to each loop. So, click on the Next step, and select Apply to each action. Then in the value set the varArray from the dynamic content.

Now we will create the array of items in the SharePoint list, so click on the Add an action inside the loop and select Create item.

Then provide the site address, list name, and in title select the current item of the Apply to each from the dynamic content.

Next, click on Save and run the Flow manually, once your flow ran successfully

After the flow ran successfully, go to the SharePoint list, you can see loop control create an item from the array to the list.

This is an example of a Power Automate array variable apply to each.
