Convert THMX to HTML

Can you convert THMX to HTML?
QUICK ANSWER
Is it possible to convert THMX to HTML?
No - not a direct conversion.

A theme is styling metadata (color/font/effect schemes), not page content, so there is no meaningful theme-to-HTML conversion. To get HTML, apply the theme to a document and export THAT document as HTML. db lists html with software_count 0.
