Thanks Christophe, that's what I thought.
Just seemed weird that they were 'disordered' in exactly the same way every time.
FYI, as of Python 3.7, dicts are ordered.
The problem is that we are possibly going to have many versions of these forms with slightly differing keys, which will be a pain to order in some hard coded way.

JSON objects, like Python dicts, are not automatically ordered by key. Once you move from the column space to the JSON object space, you can't rely on the object keys being in a consistent order.
You'll want to have a step when ingesting the JSON object into a report that lines up the key values appropriately with the right presentation in the report. -- -- Christophe Pettus xof@thebuild.com
Sounds like you’ll need a separate mechanism for maintaining versions of the forms and which headers represent the same data concept. Always access data via canonical header translated to current form.
