Why the Visual Composer WordPress plugin does not work with WP-API

I’m trying to import content from a site developed in WordPress + visual composer, in the pages are importing visual composer tags … Enclosed a screenshot … can I filter or remove these tags? The generated json files seem to be seen as text

This doesn’t seem to have anything to do with Ionic. You would better post this at a forum about Wordpress, Visual Composer or WP-API. There is also a StackOverflow for Wordpress: https://wordpress.stackexchange.com/

the same problem appear for me .
do you solve it
