Hello Muhammad,

If you are talking about bootstrapping data using an Excel File then : 

"Service Studio creates:

• An action with the bootstrap logic named "Bootstrap" in the Server Actions folder in the Logic tab.

• A structure with the content of the Excel file named "Excel_" in the Structures folder in the Data tab.

• A resource with the Excel file in the Resources folder in the Data tab.

• A timer to execute the action at publish time named "Bootstrap" in the Timers folder in the Processes tab."

So Outstyems creates 1 action for each file.

You can read more about this in this post: Bootstrap an Entity Using an Excel File.

I hope it helps!
