Office2 supports importing XLS (BIFF5 through BIFF8), XML Spreadsheet format and CSV format. When saving a file, the file format will be maintained. For example, if you import and open a .xls file, when you save it, it will remain a .xls file. If you import and open a .xml file, when you save it, it will remain a .xml file.
