Power Query: Import text files content into a single cell of each row

[ashley12]

I'm trying to import txt files into excel. All of the text has the same pattern. That's why I want the content of each file to be in a single cell, so later I can use "Add column from example" to extract the piece of information I need. However, the content was imported into multiple rows for each files (image attached). Could someone help me resolve this problem? Thank you
