WordPress Content Export (XML to Clean Text)

Im closing down my website. I want to keep the written content. I need a WordPress specialist to extract and convert content from existing WordPress XML exports into clean, readable text documents.

The website contains pages exported as WordPress XML. Much of the content is mixed with shortcodes, page builder markup (e.g. WPBakery, VC), and encoded elements. I need the human-readable content only, organised and usable. There are 370 pages on the site that simply need exporting and converting to one wordpress document. As soon as conveniently possible is great. Thanks for reading.
