Help reformatting posts in WordPress

We have exported 150 posts from an old WordPress site that used Cornerstone (https://theme.co/docs/cornerstone-overview) into a new WordPress site. The import was successful and it has carried across all the posts including titles, categories, and feature images, but the main post editor fields are now filled with shortcodes that were used in Cornerstone to format the post. I need someone to go through these posts and remove these shortcodes, reformatting the post with any inline styles such as bold, italics, quotes, and adding in any inline images. You'll be able to see the front end of the original website for visual reference. Screenshot attached of some of the shortcodes that appear in a post.
