| Description | 🔵 The `.csv` (Comma-Separated Values) format is a straightforward text format used for presenting tabular data. Each line in this format represents a row in a table, and the individual fields within a row are separated by specific characters called delimiters. The most common delimiter is a comma, but semicolons or tabs can also be used. As a simple text format, it's universally compatible and easy to edit. A CSV file consists of rows and fields, separated by the chosen delimiter, without any predetermined structure. All data within the file is treated as text strings, which is fundamental to how data is handled in the `.csv` format. |
| Technical details | 🔵 You can add optional headers to `.csv` files, and it supports various text encodings, such as UTF-8 and ASCII. If a field includes delimiters, it's usually enclosed in quotation marks. Any quotation marks within the field are "escaped," meaning they are read as regular text rather than special characters. While the `.csv` format isn't ideal for managing complex or linked data structures, its simplicity and versatility make it a popular choice for basic data exchange and import/export tasks. The `.csv` format works well with common software, including spreadsheets and databases, which contributes to its continued use for straightforward data tasks. The simplicity and adaptability of this format significantly contribute to its widespread use. In summary, the `.csv` format is a popular choice for basic data handling and transfer tasks because of its simplicity, versatility, and high compatibility. |

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. |
