What is XLS format?

XLS (Microsoft Excel Spreadsheet)

The XLS file format is a proprietary binary file format developed by Microsoft for its Excel spreadsheet application. Initially introduced with Excel 2.0 in 1987, XLS has been widely used for storing and managing data in a structured manner. The format supports various features including calculations, charts, and pivot tables, allowing users to perform complex data analysis.

XLS files can contain multiple worksheets, each consisting of rows and columns where data can be entered. The format supports a variety of data types, including text, numbers, dates, and formulas, enabling users to create dynamic spreadsheets that automatically update based on changes to the data.

Despite its popularity, the XLS format has some limitations, such as file size restrictions and lack of support for certain modern features available in newer formats like XLSX. The latter format, introduced in Excel 2007, uses an XML-based structure and offers improved data management capabilities, making it the preferred choice for many users today.

However, XLS files remain widely used in legacy systems and among users who have not transitioned to the newer formats. The format's compatibility with older versions of Excel ensures that many users can still access and work with their data without needing to upgrade their software.

In addition to Excel, various other applications and tools can open XLS files, making it a versatile format for data sharing and collaboration. Overall, the XLS format continues to play a significant role in the world of data handling and analysis, despite the advancement of technology and file formats.
