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.
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.
Did a workaround. For what I needed, I used the python dict to json function, which creates a string, and then stored that string in a varchar column on the DB, leaving the json in place for other use.
For reporting, pulled the varchar back and used the json to dict function on python. Minimal code changes required.
The output is formatted into an Excel spreadsheet, writing the column header / title from the dict keys, and then formatting the values underneath.
Not exactly 3rd normal form and all the other best practices, but this is a hard prototype we have some customers for, so ease of being able to iterate multiple forms and changes is key.
