How Microsoft lost the office file format battle

There are two main ways to fail at the standards game: You can create software that handles documents in formats for which no true standards exist, or you can create a standard that exists only on paper and in committee, with no reference software implementation. Amazingly, for all its hype and bluster, with OOXML Microsoft has managed to do both.

I couldn't describe it better. OXML seems to be a dead standard at this point! Even if it it's no longer "MS OOXML" and is managed by ISO. In short: OOXML is defective by design

Fractured YEARFRAC and Discounted DISC

It is obvious that Excel OOXML has currently many small, but serious flaws:

In fact the problems described makes me think about throwing away the whole MS Office 2007 forever! Boy, am I glad I have never installed it. :-)

OOXML ISO aftermath in Poland

Not even ordinary people and experts in the field find the OOXML standardization procedure scandalous. Even members of the country standardization committees have concerns. Just read the letter to the president of the Polish Standardization Committee:
