MSG

Microsoft Outlook Email Format

The MSG is a file format used by Microsoft Outlook to store email messages, including attachments, headers, and metadata. It is primarily supported by Microsoft Outlook and other Microsoft Office applications, but can also be accessed using third-party tools like LibreOffice, Thunderbird, or specialized MSG viewers. The format stores data in a structured binary format, preserving email properties such as sender, recipient, subject, and timestamps, while also supporting advanced features like embedded objects, RTF formatting, and custom properties.

XLSB

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.
