Hi @marcomizz,
Do you want to copy item to different excel files at the same time?
If so, I think you need to list different tables at the same time, here is a simple demo for your difference:
I use the trigger when an item is created or modified, if you just create new items, you could use the when an item is created instead.
For the condition, just to check if the common column in your Excel table has existing value, in my scenario, Title is the common column between SP list and Excel table, if the new created Title equals to any Title in excel file, just update the existing row in Excel, otherwise, created a new row.
