Converting Google Docs document into HTML or webpage has never been easier (also it might have not been possible 😉 ).
So, in order for you to convert Google Docs into webpage, we are going to be using functionality called Publish to web.
1. Open up your Google Document
2. Click File -> Publish to web
3. Click “Publish”
4. Copy your link
Once you click the blue button Publish, a public link for your document will be generated and once you visit the link, it will display your document in the HTML format.
The web document gets automatically updated once you update the text inside the original document.
Hope this helps!
