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🔵 .docx The .docx format is the default file format for documents created in Microsoft Word starting with Word 2007 and later versions. It is part of the Office Open XML specification and uses XML and ZIP compression to create smaller file sizes. The .docx format supports text, images, styling, and complex document formatting. Compared to the older .doc format, it is more modern and open, and has become the standard for word processing documents in many environments.
Technical details🔵 The `.docx` format, introduced with Microsoft Office 2007, replaces the older `.doc` format in Microsoft Word. It is built on the Office Open XML standard, utilizing XML to outline the structure and content of the document, which makes it more transparent and easier to work with. `.docx` files are essentially zip archives that contain XML files and resources, organized into folders such as 'word', 'docProps', and 'rels' for text, properties, and relationships. The main text is stored in `document.xml`, while styling information is located in separate files like `styles.xml`, and there are directories for embedded media. This format enhances compatibility between different software platforms, reduces file sizes, and improves the recovery of corrupted files. Most modern word processors support the `.docx` format, and Microsoft provides compatibility packs for older versions of Word. For security reasons, macros are stored in a separate `.docm` file. Overall, `.docx` represents a significant advancement in document format technology, promoting transparency, compatibility, and efficient data management.
