Convert HTML to XLSX

.html

HTML – is a special format associated with web pages developed using the appropriate markup language. Links link a lot of pages from websites. Text editors modify files with a similar extension since they are a standard text document. However, to avoid incorrect display, it is recommended to use specialized software, for example, Adobe Dreamweaver. All modern browsers allow you to open HTML files, but the source code is not displayed by default. It can be viewed in the web browser menu by selecting the "View source" category or using a text editor. Files with the HTML extension include text content and links in the form of text to external objects, for example, a picture inside an article.

The HTML language was created by T. Berners-Lee to exchange scientific and technical information by people who do not have in-depth knowledge in the field of imposition. It is based on the use of multiple tags enclosed in angle brackets. Modern browsers easily interpret the HTML4 language by providing the user with formatted text. Now there is a fifth version with the DOM specification (formerly SGML).
