XLSX

Microsoft Excel Open XML Spreadsheet

XLSX is a widely used file format for spreadsheets, developed by Microsoft as part of the Office Open XML standard, succeeding the older XLS format. It is supported by Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications, ensuring cross-platform compatibility. The format is based on XML and stored in a compressed ZIP container, enabling features like advanced formulas, charts, conditional formatting, and support for large datasets while maintaining smaller file sizes compared to its predecessor.

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.
