EML

E-Mail Message File

The EML file format is a standard for storing email messages, widely used for archiving and sharing emails across different platforms. It is supported by various email clients like Microsoft Outlook, Mozilla Thunderbird, and Apple Mail, as well as web-based tools and email servers. The format is plain text-based, typically encoded in MIME (Multipurpose Internet Mail Extensions), allowing it to store email content, attachments, headers, and metadata in a structured and interoperable manner.

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.
