Microsoft Excel Binary File Format

Extension	.xls
Category	🔵 documents
Programs	🔵 Microsoft Office 🔵 LibreOffice 🔵 Kingsoft Office 🔵 Google Docs
Main program	🔵 Microsoft Office
Description	🔵 The .xls format is the default file format for spreadsheets created in Microsoft Excel, particularly in versions before Excel 2007. 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 data. The .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 used for Microsoft Excel versions before 2007, stores spreadsheet elements such as worksheets, formulas, and macros. Being a proprietary binary format created by Microsoft, its undocumented internal structure has made compatibility with third-party software quite challenging. This format consists of binary records that contain data, formatting, and embedded objects, allowing for multiple worksheets, various functions, and inter-sheet referencing. `.xls` files can also include Visual Basic for Applications (VBA) macros, which enable automation and complex calculations. While supported in applications like OpenOffice Calc, there are options available to convert between `.xls` and other formats such as `.xlsx`. Despite security concerns related to macros, `.xls` is still commonly used due to its compatibility with older Excel versions and legacy systems. However, the newer `.xlsx` format, introduced in Office 2007 and utilizing XML and ZIP technologies, offers improved efficiency and security features.

Office Open XML Document

Extension	.docx
Category	🔵 documents
Programs	🔵 Microsoft Office 🔵 LibreOffice 🔵 Kingsoft Office 🔵 Google Docs
Main program	🔵 Microsoft Office
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 based on the Office Open XML standard, utilizing XML to outline document structure and content, which makes it more transparent and easier to process. `.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 located within `document.xml`, while styling is stored in separate files like `styles.xml`, and directories house embedded media. This format promotes interoperability, reduces file sizes, and enhances recovery from corruption. Most modern word processors support `.docx`, and Microsoft provides compatibility packs for older Word versions. For security reasons, macros are stored in a separate `.docm` file. `.docx` represents a significant advancement in document format technology, with a focus on openness, interoperability, and efficient data management.
