How to display all parameters to which GPOs apply?

Question

System administration

I came to an office with a bunch of GPOs where there were a lot of admins and everyone just entered what they wanted, so there are policies called "This is here because others don't work without it (for some reason)"
Is there software that can get through all the GPOs that are created and create a table that will list all the parameters that are controlled by the GPO, their values, to whom they apply and in which policy they are specified (the same parameters can be specified in different policies)
I want to find duplicates, conflicting parameters and optimize the total number of rules
