I don't know what the standard tools are, but I'm sure it would be a trivial
mechanical transform to go between
Therein lies the problem - there are no "standard tools" nor any way to specify a cross-platform mechanical transform for JSON (at least not yet).
Enter the externalisation in the form of expensive consultants required to implement $PREFERRED_FORMAT in $PREFERRED_LANGUAGE, which is one of a number of areas where oversimplification actually ends up biting the users.
Note that short of implementing each format for each language, there's absolutely nothing we can do to help them here.
