I'm going to say "yes", but it is contingent on what your markup looks like.  Please post a representative example.

Thanks. That makes sense

If it's helpful, I use the VBA code below to convert Word to simple HTML. The code handles hyperlinks, bold, italic and underline formatting, standard Word heading styles (Heading1, Heading2 etc) plus bulleted and simple numbered lists.

It does not handle tables or images, though it could be extended to do so fairly easily. There are four routines and a function (which creates a closing HTML tag).

The main routine calls the others.

In essence it does the following:
  • Works with your current word selection
  • If nothing is selected it converts the whole document
  • Converts Word hyperlinks to HTML setting the html target to "_blank"
  • Runs through all paragraphs in the selection and
  • - Converts lists to their HTML equivalent
  • - converts ordinary paragraphs to <p> tagged HTML
  • - converts Heading1 to <H1> etc
  • Calls another routine to search for and convert bold, italic and underline Word formatting to HTML tags

Hope it is useful
