How can I convert JSON to CSV?

Question

I have a JSON file I want to convert to a CSV file. How can I do this with Python?

I tried:

import json
import c

JSON can represent a wide variety of data structures -- a JS "object" is roughly like a Python dict (with string keys), a JS "array" roughly like a Python list, and you can nest them as long as the final "leaf" elements are numbers or strings.

CSV can essentially represent only a 2-D table -- optionally with a first row of "headers", i.e., "column names", which can make the table interpretable as a list of dicts, instead of the normal interpretation, a list of lists (again, "leaf" elements can be numbers or strings).

So, in the general case, you can't translate an arbitrary JSON structure to a CSV. In a few special cases you can (array of arrays with no further nesting; arrays of objects which all have exactly the same keys). Which special case, if any, applies to your problem? The details of the solution depend on which special case you do have. Given the astonishing fact that you don't even mention which one applies, I suspect you may not have considered the constraint, neither usable case in fact applies, and your problem is impossible to solve. But please do clarify!
