Le lien vers cette étude de Franz Müller a été posté par Rony Flatscher sur la liste sc@ooo, elle est donc en anglais, mais vaut vraiment le détour.

L'abstract :

"This paper tries to assess the executing of Microsoft Excel (Excel) macros and functions in OpenOffice.org Calc (Calc). The interoperability between Excel and Calc could be a very interesting issue for businesses as well as for individuals, because OpenOffice.org (OOo) can be used entirely free of any license fees WhyOO. To assess the extent of interoperability, an Internet research was made and several workbooks were created in Excel which contained functions and macros. These Excel workbooks were afterwards opened with and saved in Calc and the examples in it were tested."
