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. |

| 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. |
