MHTML

MIME Encapsulation of Aggregate HTML

MHTML (MIME HTML) is a web page archive format that combines HTML, images, scripts, and other resources into a single file for easy storage and sharing. It is supported by web browsers like Microsoft Edge and Internet Explorer, as well as tools such as email clients and web development software. The format uses MIME encoding to embed external resources directly into the file, enabling self-contained web pages with advanced features like CSS, JavaScript, and multimedia elements.

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.
