More info

The standard format of Excel 2007 and 2010 is the XML based Open XML document with the extension xlsx. The binary format has the advantage of occasionally being smaller and being opened faster by Excel. The disadvantage is the lower compatibility with other Office suites.

For the Office versions 2000, 2003 and XP, however, this functionality can be used with the help of the Microsoft Office Compatibility Pack, whereby the result of an imported XLSB file does not always have to correspond to 100% of the original.
