HTML to DOCX conversion using C#

html to docx conversion logo

HTML is the older and one of the reliable formats for sharing information over the internet as most browsers support it as the default rendering format. Owing to its high adaptability, many browsers started supporting it as a standard format. The HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. An HMTL document is comprised of HTML elements which are considered as their building blocks. It includes forms, text, images, animations, links, etc. The HTML elements are referenced from external/third-party websites and are loaded at runtime (when the document is loaded in the browser).

Nevertheless, we convert HTML files to a format supporting long-term document preservation. Or, you may have a requirement to convert the files into a format that shall be easily shared with other fellows, so that they can enter their feedback. One of the popular formats for office file data storage is MS Word (DOCX, DOC, DOCM, DOT, DOTX, DOTM) or even RTF, OpenOffice (ODT, OTT) formats.
