Как конвертировать DOCX в HTML на C# и .NET

  1. Добавьте SautinSoft.Document из Nuget.
  2. Загрузите входной документ.
  3. Сохраните в формате HTML.

SautinSoft.Document может помочь Вашему приложению преобразовать документ из одного формата в другой.
Вам нужно будет только Load() документ и Save() в нужном формате:


            DocumentCore dc = DocumentCore.Load("...");
            dc.Save("....");
