The source code of fpspreadsheet is open ... just copy/paste/modifiy it for your needs:
https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/components/fpspreadsheet/xlsbiff8.pas#l50 But BIFF8 is not a simple format, there is no simple answer to your question. It is encapsulated in a OLE Document storage system to start with, which is something pretty complex. BIFF2 till BIFF5 (Excel 5.0) were simple formats, but that's not the format you are looking for from your question.
