Best way to remove hyperlinks in data?

I have a bunch of elements that all have useless hyperlinks. How do I strip them efficiently?

I really like using Scapple for moving things around.

I made a table of contents from a word file that just listed the top level styles. Then I cut an pasted this into Scapple and cut it up for items to move around.

Relational reference really helped me plan the document. Thank you.
