CHM

Microsoft Compiled HTML

The CHM file format was developed by Microsoft for storing and displaying online help documentation, combining multiple HTML pages into a single compressed file. It is commonly opened using Microsoft's HTML Help Viewer, but third-party tools like 7-Zip or SumatraPDF can also extract or view CHM files. The format supports a hierarchical table of contents, full-text search, and embedded multimedia, making it a versatile solution for organizing and accessing help content efficiently.

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.
