Hi @deerzzxdell ,
According to your description, you want to add the excels' rows to the Dataverse.And you turn off the "Split on" options.
So your Trigger supports fetching multiple Excel files at the same time. But according to my tests, the return value of this trigger is not the content of the file, but some information about the file:
So, if we want to get the content in the corresponding excel, we still need to use Apply to each to get the data in each file, and then use Apply to each to add each row to our Dataverse.
Here are the steps you can refer to :
(1)This is my two test files:

And this is my dataverse table:

(2)My flow is like this:

Then we can make the data in our excels to Dataverse Table:
