Hi,
Yes but you have many details missing.
1) Do you want this to run at a certain time of day, or week or is it manually triggered?
Its easy to do as long as the following
1) that the Spreadsheet that has the source data has an excel table wrapped around it AND that the Excel you want to paste too, also has a Table around the rows
you want to add too
2) then in your flow you would do
List rows from a Table (Excel Action). specifying the correct table
3) add an apply to each with the input being the output of step 2
4) for each Loop.
use Add row to a table (excel action)
where you populate the data for excel from the Apply to Each Loop
And done.
Its not hard but you have things that have to exist, such as the Tables I mentioned, knowing the location of the files etc.
