Great idea! That would be a really nice way to do  the actual conversion, 
since it would lead to consistent results (no separate import/export 
logic). And a plugin-interface for custom datastore export formats would 
be really nice, too.

That still leaves the question on how to offer this separate format to the 
users. For example, if one wanted to create separate XSLX-copies of 
CSV-resources then these need to be created and kept in sync. Any ideas 
for that or for other UI approaches?

Regards,
Florian
