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 OpenDocument Spreadsheet (ODS) file format is an open standard for storing spreadsheet data, part of the OpenDocument Format (ODF) family, designed for interoperability and long-term data preservation. It is natively supported by applications like LibreOffice Calc, Apache OpenOffice, and Google Sheets, as well as being compatible with Microsoft Excel through import/export functionality. The format uses XML-based file structure, enabling features such as formulas, charts, conditional formatting, and macros, while maintaining a compact and efficient storage system for complex data.
You can also convert CHM into many other file formats. Please see the complete list below.
