All very good questions, I'd say just create an empty
document/spreadsheet/presentation, set the export type to the identified one,
and do an export+import cycle. Out of that the last step is optional if it'd be
a larger task, the most important is to start in the correct application and
set the correct save format.

While I think the above method would be applicable to most formats, it's really
relevant for the formats that could come in as 0-byte files in real life, ie.
the ones that can be created by MS Office via Explorer context menu.
