Comma Separated Values File

Extension	.csv
Category	🔵 documents
Programs	🔵 Microsoft Excel 🔵 Microsoft Works 🔵 Corel Quattro Pro 🔵 Apache OpenOffice 🔵 LibreOffice 🔵 Microsoft Notepad 🔵 Libre Office 🔵 MobiSystems OfficeSuite Pro 7
Description	🔵 The .csv (Comma-Separated Values) format is a simple text format used to represent tabular data. Each line in the file corresponds to a row in the table, with columns separated by commas. This format is widely supported by various applications, such as spreadsheet and database software. It is commonly utilized for transferring data between different programs, as well as for exporting and importing large volumes of data due to its ease of use and high compatibility.
Technical details	🔵 The `.csv` (Comma-Separated Values) format is a straightforward text format used for tabular data. In this format, each line represents a row in the table, with fields separated by a delimiter. Typically, a comma is used as the delimiter, but semicolons or tabs can also be used. Being a plain text format, it is universally compatible and easy to edit. The structure of a csv file consists of rows and fields delimited by the chosen delimiter, without a standard schema. All data is treated as strings, with interpretation depending on the application importing the data. Optional headers can be included in `.csv` files, and various text encodings such as UTF-8 and ASCII are supported. When fields contain delimiters, they are usually enclosed in quotes and any internal quotation marks are escaped. Despite not being suitable for complex or relational data structures, the simplicity and flexibility of the `.csv` format make it popular for basic data exchange and import/export tasks across different programs. Its compatibility with common software, including spreadsheets and databases, ensures that it remains favored for straightforward data operations.

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.
