Microsoft Excel Binary File Format

Extension	.xls
Category	🔵 documents
Programs	🔵 Microsoft Office 🔵 LibreOffice 🔵 Kingsoft Office 🔵 Google Docs
Main program	🔵 Microsoft Office
Description	🔵 .xls The .xls format is the default file format for spreadsheets created in Microsoft Excel, particularly in versions before Excel 007. This binary file format can store data in cells organized in rows and columns, and it supports formulas, charts, graphs, and various formatting features to manipulate and visualize dataThe .xls format was commonly used in business, finance, and any field requiring data analysis and presentation but has since been largely replaced by the more advanced .xlsx format.
Technical details	🔵 The `.xls` format, primarily for Microsoft Excel versions before 2007, stores spreadsheet elements like worksheets, formulas, and macros. As a proprietary binary format by Microsoft, its undocumented internal structure made third-party software compatibility challenging. This format includes binary records encapsulating data, formatting, and embedded objects, supporting multiple worksheets, various functions, and inter-sheet referencing. `.xls` files may contain Visual Basic for Applications (VBA) macros, enabling automation and complex calculations. It's supported not just in Excel but also in applications like OpenOffice Calc, with options to convert between `.xls` and other formats like `.xlsx`. Despite security concerns with macros, `.xls` is still used, mainly for its compatibility with older Excel versions and legacy systems, although the newer `.xlsx` format, introduced in Office 2007 with XML and ZIP technologies, offers improved efficiency and security.

Description	🔵 .html (Hypertext Markup Language) The .html format is the standard markup language used for creating web pages and web applications. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. It provides the basic building blocks for webpages, allowing for the integration of text, images, multimedia, and other elements. HTML files are the backbone of the World Wide Web and are interpreted by web browsers to display content.
Technical details	🔵 The `.html` (HyperText Markup Language) format is a key technology for developing web pages and applications, enabling the structuring of web content. It uses tags to define elements like headings, paragraphs, links, and images within a webpage. HTML documents start with a doctype declaration, followed by ``, ``, and `` sections. HTML has evolved over the years, with HTML5 being the latest version that supports multimedia, semantic elements, and complex web application APIs. It uses character encodings like UTF-8 for worldwide character representation. HTML is typically used alongside Cascading Style Sheets (CSS) for visual styling and JavaScript for dynamic interactivity. Governed by the World Wide Web Consortium (W3C), HTML ensures consistent browser rendering and supports accessibility features for wider access. Its semantic tags also play a crucial role in search engine optimization (SEO). The combination of HTML's simplicity with CSS and JavaScript functionalities establishes it as a foundational element in web design and development.
