What is an XLSB file?
The XLSB (Excel Binary Workbook) format is a binary implementation of the Office Open XML (OOXML) standard, introduced with Microsoft Office 2007. Unlike XLSX, which parses XML text files, XLSB stores data in binary parts within a ZIP container, resulting in faster load times and reduced file size for massive datasets containing complex formulas. It supports all Excel features, including VBA macros, but is less interoperable with non-Microsoft parsers due to its binary nature.
How to open an XLSB file
Opening XLSB files requires Microsoft Excel 2007 or later for optimal performance and macro execution. While Windows and macOS rely on the Office suite, Linux users can utilize LibreOffice Calc, which supports reading and writing XLSB files, though execution of embedded proprietary VBA macros may be limited or require code adjustments.

What is a PDF file?
The Portable Document Format (PDF) is a comprehensive file format, standardized as ISO 32000, designed to present documents consistently independent of application software, hardware, and operating systems. It encapsulates a complete description of a fixed-layout 2D document, including text, fonts, vector graphics, and raster images, based on the PostScript language. Advanced implementations support interactive form fields, JavaScript scripting, 3D objects (U3D/PRC), and various encryption standards.
How to open a PDF file
PDF viewing is natively supported by all major modern web browsers (Chrome, Edge, Firefox, Safari) and most operating systems via built-in previewers. For advanced manipulation, form filling, or pre-press validation, dedicated software such as Adobe Acrobat DC, Foxit Reader, or open-source tools like Ghostscript and Poppler is required.
