In my company usage of Confluence, I noticed that many users don't use Confluence because it don't have variables and math operations, so they use Excel instead.

I think that, implementing that in Confluence, could collaborate to users create pages directly in Confluence, without the need to import lather, or even exclude and ctrl+c ctrl+v in Confluence, with formulas been resolved.

This could integrate to some JIRA issue fields to, but I'm not shure of this usage.
