When you copy a paragraph from a PDF file organized in two columns, similar to (1), and paste it into MS Word, you get something similar to (2).
How can you get a normal paragraph without those ugly line breaks and get something similar to what is shown in (3)?
It is very simple. After pasting the text into MS Word, find and replace all the ^p with a blank space (highlighted with blue in the picture below).
After clicking on “Replace All”, MS Word will arrange all the lines for you.
