Microsoft Office (2010) displays the spreadsheet (also without drawings) but removes all the formulas, showing just the values,
Known. MS-Excel 2010 did not implement the formula part, to their "excuse" as it wasn't specified with ODF 1.0 (ISO/IEC 26300:2006) and they purposely implemented only what was specified in the ISO standard. However, with Excel 2013 they implemented OpenFormula of ODF 1.2, so if you want ODF spreadsheet interoperability you need MS-Excel 2013.
