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 synonymous with spreadsheets created in Microsoft Excel, especially in versions prior to 2007. This binary file format has the capability to store data in cells that are systematically arranged in rows and columns. It's also flexible enough to support formulas, charts, graphs, and a plethora of formatting features to assist with data manipulation and visualization. The .xls format was a common go-to in sectors such as business and finance, or any field that necessitated data analysis and presentation. However, the advent of the more sophisticated .xlsx format has largely overshadowed its use. |
| Technical details | 🔵 Diving into the technical details, the .xls format, the golden standard for Microsoft Excel versions prior to 2007, is capable of storing a range of spreadsheet elements, including worksheets, formulas, and macros. As a proprietary binary format birthed by Microsoft, its undocumented internal architecture has posed a significant challenge to compatibility with third-party software. The format is comprised of binary records that contain data, formatting, and embedded objects, offering the possibility of multiple worksheets, a variety of functions, and inter-sheet referencing. .xls files also have the capacity to include Visual Basic for Applications (VBA) macros, opening up avenues for automation and complex calculations. Despite the existence of alternatives like OpenOffice Calc, and options to convert between .xls and other formats such as .xlsx, the .xls format continues to hold its ground, largely due to its compatibility with older Excel versions and legacy systems. However, it's important to note that the newer .xlsx format, which made its debut in Office 2007 and harnesses XML and ZIP technologies, brings to the table improved efficiency and security features. Despite the potential security risks associated with macros, the .xls format continues to be widely used. |

OpenDocument Spreadsheet
| Extension | .ods |
| Category | 🔵 documents |
| Programs | 🔵 Microsoft Office 2007 🔵 Microsoft Office 2010 |
| Main program | 🔵 OpenOffice Calc |
| Description | 🔵 The `.ods` (OpenDocument Spreadsheet) format, compatible with LibreOffice Calc, OpenOffice Calc, and other office suites that adhere to the OpenDocument standard, is a file type based on XML. It serves as an open-source alternative to restricted formats like Microsoft's .xls and .xlsx. ODS files can hold sophisticated spreadsheets with cells, rows, columns, formulas, charts, and graphics. They are mainly used in environments that use open-source software. |
| Technical details | 🔵 In the realm of OpenDocument Format (ODF) for office documents, the `.ods` format plays a crucial role. It includes key components like standardization – the OASIS (Organization for the Advancement of Structured Information Standards) and ISO/IEC (ISO/IEC 26300) standardize the ods format, offering a public specification and an open development process. XML-based – the format comprises compressed XML files, effectively forming a ZIP archive, which promotes reliable data transfer and interoperability. Spreadsheet components – it supports spreadsheet cells, rows, columns, formulas, charts, and sophisticated formatting options, including conditional formatting and cell styles. Macro capabilities – it supports the addition of macros in various scripting languages, although this carries potential security hazards. |
