MS Excel 97 2000 XP to RGF conversion is the process of transforming spreadsheets saved in the legacy XLS binary format (used by Microsoft Excel 97–2003, commonly encountered as 'Excel 97 2000 XP') into the RGF format. This conversion extracts worksheet data, cell values, formulas, and basic formatting from the XLS file and saves it in the RGF container so the data can be read or processed by RGF-compatible tools.
