As I've shown, in the rush to write a 6,000 page standard in less than a year, Ecma dropped the ball. OOXML's spreadsheet formula is worse than missing. It has incorrect formulas that, if implemented according to this standard, would raise important health, safety and environmental concerns, aside from the obvious financial risks of a spreadsheet that calculates incorrect results. This standard is seriously messed up. Shame on all those who praised and continue to praise the OOXML formula specification without actually reading it.

What will happen when health risks emerge?
