Microsoft Excel Binary Spreadsheet File

XLSB is a binary file format used by Microsoft Excel to store spreadsheet data, offering a more compact and efficient alternative to XML-based formats like XLSX. It is primarily supported by Microsoft Excel and a few third-party tools, such as LibreOffice and Apache POI, though compatibility may vary. The format stores data in a compressed binary structure, enabling faster loading and saving times, and supports advanced Excel features like macros, charts, and complex formulas while maintaining smaller file sizes compared to XML-based formats.
