Can you make it possible to edit your libraries (especially for tv-shows) through a text editor or spreadsheet please?
As you can see in the uploaded picture, the paths are too long so the end is not completely visible and if you go to the end of the row, the season number is hidden by the cross to remove the path… Meaning there is no overview of what you have added and you have no control over the order as well, since you can’t sort it.
Where is this data stored now, maybe it can already be edited like this?
It is, in a roundabout way. That help document links to the “Your Media” help document which, of course, includes the “Naming and Organizing Your TV Show Files” page (which the OP linked as a reference). That page notes that directory containing all series should be the folder added.
I see your point but tend to agree with @philipsw…
The article is quite specific:

In the above example, it is the main folder of each type of content (e.g. /Movies , /Music , /TV Shows ) that you would specify as the content location for that library type.
