XLSX

Microsoft Excel Open XML Spreadsheet

XLSX is a widely used file format for spreadsheets, developed by Microsoft as part of the Office Open XML standard, succeeding the older XLS format. It is supported by Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications, ensuring cross-platform compatibility. The format is based on XML and stored in a compressed ZIP container, enabling features like advanced formulas, charts, conditional formatting, and support for large datasets while maintaining smaller file sizes compared to its predecessor.

HTML

Hyper Text Markup Language

HTML is a standard markup language used to create and structure content on the web, enabling the display of text, images, links, and multimedia in web browsers. It can be edited using simple text editors like Notepad or specialized tools like Visual Studio Code, Adobe Dreamweaver, and online platforms such as CodePen. HTML files consist of elements defined by tags, which organize content into headings, paragraphs, lists, and more, while advanced features like forms, multimedia embedding, and integration with CSS and JavaScript enhance interactivity and design.
