[Libreoffice-bugs] [Bug 144732] [FILEOPEN] Missing content from bare BIFF8 XLS Files

--- Comment #10 from SheetJS <dev at sheetjs.com> ---
The spec situation is confusing.  The old 97-2007 spec [1] (page 18) refers to
a "Simple Save" structure.  Our initial interpretation was that the Simple
files have no mini FAT.

Daniel Rentz and the OpenOffice developers [2] (page 14) may have interpreted
that as bare workbook streams:

> All document types and BIFF versions can be stored in a simple stream file, most of them are always stored this way.  The only exception are BIFF5-BIFF8 workbook documents, which are usually stored as compound document files (see below). If these documents are stored as stream files, the entire file consists of the “Book” stream (BIFF5) or “Workbook” stream (BIFF8) only.
