What is CAB file format?

CAB (or Cabinet) is a common file format used to compress and archive files, commonly used in Microsoft Windows. CAB files are created using the MakeCab command-line tool that is included in Windows and also supported by other compressed file programs. CAB files contain one or more compressed and/or encrypted files in the cabinet format. This format uses embedded file pointers that can be securely transported without being extracted, making them a popular choice for software publishers and developers who need to deliver files in a self-contained package. CAB files can also be distributed via a server, or downloaded from the Internet and then installed. CAB files are ideal for storing and transferring large files, as they can easily be compressed to reduce the file size. The files also remain secure due to their internal file pointers, as they cannot be opened or accessed without the proper software. In addition, CAB files are great for a software publisher who needs to deliver large files quickly and efficiently.

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.
