Parse HTML data into String from WP REST API

Hi, I’m trying to get JSON data from http://techinflux.com/wp-json/wp/v2/posts. The content in { excerpt -> rendered } are in HTML format. Since I’m using WP REST API, I can’t do anything about parsing HTML to string from website.

Is there any solution that we can parse HTML data into String. One possible solution might be using JQuery, Is it possible to use jQuery in Fuse? Or is there any other solution that we can fix this problem?

Please explain the inputed data you want transfered and the expected result
