XLSX – is an e-book created with one of the versions of the Excel program older than 2007. Thus the data have the form of tables consisting of columns and lines. Each table is divided into cells with a unique address, consisting of numeric and alphabetic characters. Cells contain data, both manually entered, and information that was obtained as a result of calculations. The extension allows the use of images, diagrams, and graphic information. XLSX files are formatted based on the Open XML standard, which will enable you to compress data by the type of ZIP. The archive contains a file for describing the table and individual files for each of its worksheets. The format makes it possible to develop and edit complex multi-sheet spreadsheets with various formulas and data sources.

Using the XLSX extension helps to optimize the file's content, the technology of managing, and restoring information. The format significantly increases the capabilities of binary files of obsolete Excel program variants. All applications that display XML can work correctly with the XLSX extension. Due to the preservation of data in XML format, reliable data storage is provided. This allows you to transfer files over local networks seamlessly.

.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).
