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 007 and later versions. It's part of the Office Open XML specification and uses XML and ZIP compression for smaller file sizesThe .docx format supports text, images, styling, and complex document formatting. Being more modern and open compared to the older .doc format, it has become the standard for word processing documents in many environments.
Technical details🔵 The `.docx` format, launched with Microsoft Office 2007, replaces the older `.doc` format in Microsoft Word. It's based on the Office Open XML standard, using XML to detail document structure and content, making it more transparent and easier to process. `.docx` files are zip archives containing XML files and resources, with folders like 'word', 'docProps', and 'rels' for text, properties, and relationships. Main text is in `document.xml`, with separate files like `styles.xml` for styling and directories for embedded media. This format enhances interoperability, reduces file sizes, and improves corruption recovery. It's supported by most modern word processors, with Microsoft offering compatibility packs for older Word versions. For security, macros are in a separate `.docm` file. `.docx` is a step forward in document format technology, emphasizing openness, interoperability, and efficient data management.
