I extracted this text box and want the results to be in different cells for every line.



You may have to check the source code of that text box. For example, if the texts were displayed as a whole between a pair of attributes <p>, as the screenshot shows, it is unsplit-able.

That is to say, if the text is actually one single element in the source code, though there seem to be multiple lines on the web page, you can't extract them by line.

Did this answer your question?
