What is XLSB file format?
The XLSB file format is a binary file format used for Microsoft Excel workbooks. Unlike the XLSX and XLSM file formats, which are based on the Open XML format, XLSB is a binary format that stores data in a binary structure. This binary structure allows for faster file processing and improved performance compared to the XML-based formats.
XLSB files contain spreadsheet data, including worksheets, formulas, charts, and other elements commonly found in Excel workbooks. The binary format optimizes storage and calculation efficiency, making it well-suited for large datasets and complex calculations. It also provides better data integrity and recovery capabilities, as the binary structure reduces the risk of file corruption.
Due to its binary nature, XLSB files are not easily readable or editable by humans. They are primarily intended for use by Excel and other applications that can read and process the binary format. However, Excel provides full compatibility and support for opening, editing, and saving XLSB files.
The advantages of using XLSB files include faster file operations, reduced file size compared to XML-based formats, and improved performance in terms of opening, saving, and recalculating complex workbooks. XLSB files are particularly useful for workbooks that involve large amounts of data or complex formulas.
