XLS kisaca
XLS
XLS is tied to the BIFF-based legacy Excel ecosystem that later gave way to OOXML-based workbook formats such as XLSX.
NCX kisaca
NCX
NCX was defined in the 2005 DAISY and ANSI-NISO talking-book standard, then carried forward into EPUB 2 and later treated as a legacy compatibility feature once EPUB 3 introduced XHTML navigation documents.
