It includes things that aren't selected, which is other random data. If I select, copy, and paste, the only desirable outcome is that I get a copy of my selection.
I don't understand what you mean. In my example I select the cells that contain 1, 2, 3, 7, 8, 9, a, b, c, then copy, then go somewhere else and paste, and Excel pastes 1, 2, 3, 7, 8, 9, a, b, c. I don't see an other data.
