These look like "pivot tables" which are well supported by Excel.
I expect that this is easy to automate with a little bit of Basic.
Of course you can build these tables with a Python script if you feel more
comfortable in Python. Then either write them into csv files ("comma
separated value", supported by the standard library)
https://docs.python.org/3/library/csv.html
which can be read by Excel -- or use a dedicated library. Google came up
