How to prefik youtube/url

How do I prefix "**www.youtube.com/**watch? while extracting the Data from youtube.
I want to extract the URL and Needed to download the videos But while extracting www.youtube.com is not getting extracted as shown in the screen.

You could add the prefix yourself. Do a for each row and change the value for column2 to the prefix+current value.

  1. string url = www.youtube.com store in a variable
  2. While iteration pass this url so it looks like
    www.youtube.com/watch?v=
