Nick McGrath, director of platform strategy for Microsoft UK, told ZDNet UK on Thursday: "In a nutshell, ODF doesn't meet the needs of Microsoft applications." McGrath said that applications such as OpenOffice, which runs on ODF, would not fully support documents created in Microsoft applications such as Office 2007, which runs on the rival Open XML standard (OXML). This echoed a comment made last week by Microsoft, where the software giant criticised IBM over its support for ODF.
"The functionality of Office and the functionality of OpenOffice — it's like chalk and cheese," said McGrath.
In a press statement on Wednesday, Microsoft said it was backing the ODF ANSI bid in the interests of interoperability.
