Wow, thanks a lot of all these solutions

I am using the new ods exporter found in 

git@github.com:kjambunathan/org-mode-ox-odt.git

And the first and the last solution work in the sense that LO can open the exported ods file while the second (string) and third (conditional) result in ods file that cannot be opened.

Given my use case, I think I will take the first solution, thanks

Again
