HTM

Hypertext Markup Language File

HTM is a file format used to create and structure content for web pages, defining elements like text, images, and links. It can be opened and edited using text editors like Notepad or specialized tools like Visual Studio Code, Adobe Dreamweaver, or web browsers for rendering. The format uses tags enclosed in angle brackets to define elements, supports CSS for styling, JavaScript for interactivity, and can include multimedia, making it the foundation of modern web development.

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.
