I have noticed rather often that in order to remove all hidden codes from downloaded (parts of) internet pages, it does not suffice to reformat the downloaded text by choosing Documents > Convert > Formatting to Default Text Style.
After this conversion, at first sight often everyting seems OK. But when I then, for instance, try to transfer the reformatted text (or part of it) to some other document (or to the Document notes panel), the old formatting emerges again, deforming the text by dividing it in columns or in other ways.
How do I remove similar ‘hidden’ formatting from dowloaded text?
