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.

MHT

MIME Encapsulation of Aggregate HTML

MHT is a file format used to save web pages as a single file, combining HTML, images, CSS, and other resources into one archive for easy storage and sharing. It is supported by web browsers like Internet Explorer and Microsoft Edge, as well as tools like Microsoft Word and specialized MHT viewers or converters. The format uses a MIME structure to embed all web page elements, including text and binary data, into a single file, often encoded in Base64, enabling offline access and preservation of web content.
