How can I Isolate headers? Thank you.

Can someone please help me? I am trying to isolate the headers in a large file and place them in a separate column. Each of the headers are distinguished with four (4) equal signs. I believe I can use this pattern to locate and extract just the headers with some excel command unbeknownst to me.

I have attached a sample file to this post, along with a more detailed explanation inside. Your help is most appreciated! Thank you.
