XLSM

Microsoft Excel Macro-Enabled Spreadsheet

XLSM is a file format used for Excel spreadsheets that support macros, enabling automation and advanced functionality within the document. It is primarily used with Microsoft Excel but can also be opened by other spreadsheet applications like LibreOffice Calc and Google Sheets with limited macro support. The format is based on the Open XML standard, storing data, formulas, and VBA (Visual Basic for Applications) macros in a compressed ZIP container, allowing for efficient storage and advanced features like conditional formatting, pivot tables, and embedded macros.

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.
