Check our videoThe 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.
The XLS file format is a binary file format used by Microsoft Excel to store spreadsheet data, including text, numbers, formulas, and formatting. It is supported by various spreadsheet applications like Microsoft Excel, LibreOffice Calc, and Apache OpenOffice, as well as online tools like Google Sheets. The format organizes data into worksheets with rows and columns, supports advanced features like macros, charts, and conditional formatting, and is part of the broader Excel ecosystem, though it has been largely replaced by the XML-based XLSX format.
You can also convert CHM into many other file formats. Please see the complete list below.
