Has anyone successfully tried PHPExcel with XLSB files?

The short research I've done on the files tonight gave me that XLSB files are basically ZIP-compressed, with worksheets saved in binary format (something called BIFF12). Pretty much the same way as XLSX-files, but XLSX stores the worksheets as .xml.

Question is, does PHPExcel support xlsb/biff12 somehow?

The simple answer is "No". At this point in time, there is no reader or writer for Excel Binary Workbooks (.xlsb files).
