You can't simply write out HTML, give it a .docx file name extension and expect Word to correctly open that document. A .docx file needs to be a valid Office Open XML package, which basically is a zip container with various XML files in it (you can easily see that by renaming a .docx document to .zip and then open it using a standard zip tool).

What you can do now to fix the problem and get a valid Word file:

  • Instead of HTML, create a valid docx file using Microsoft's Open XML SDK. There a samples included with the SDK that show you how to create Word documents with it.
  • If you can't change from creating HTML you are also able to embed HTML into a Word document using a so-called altChunk. This is described in another answer here.
  • Depending on the content that you generate, there might also be the possibility to create a template Word document, where you only need to fill placeholder. Such a solution could e.g. be build around Content Controls and Custom XML. Then you only need to replace a single XML file in the docx package to fill your document. A basic tutorial for that is available here.
