Google docs copy paste / ask a withdrawal

So, let's say I take a youtube transcript, copy everything and then paste it into a document. The way the transcription is configured with youtube is superimposed as every 5 seconds, so its lines contain about 4 to 10 words.

So on youtube it's like:

Hi hello hi hello hi hello

Hi hello hi hello hi hello

Hi hello hi hello hi hello

Hi hello hi hello hi hello

… etc

Now, when I copy everything and have "paste without formatting", it removes extra empty lines between everything and glue. Always doubled but more condensed and nothing in between.

But I want more than that. I do not want lines of text at all, I want it to be a big paragraph together. So the text above would read as follows:

Hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hello …

Is there a way to do this easily or a solution at all without manually entering and going back hundreds of times by turning a 20-page document into a 3-page document filled ..?
