I routinely copy and paste text from Acrobat to any number of other Adobe CC applications (Illustrator, PS, InDesign). When I do this, it creates line breaks where they were visually represented on the pdf, meaning when pasted into a new doc there is no flow to the text.
Is there a way in any of the programs to clear this and "concatenate" the words back together into a flowing block?

from within Acrobat? And by "line break" you mean a line feed or a break and separate point text objects?
