Why do you care about checking every value line by line? As you say
yourself, JSON data is unordered, so "line by line" is the wrong way to
compare it.
The right way is to decode the JSON data, and then compare whether it
gives you the result you expect:
a = json.load("file-a")
b = json.load("file-b")
if a == b:
print("file-a and file-b contain the same JSON data")
If what you care about is the *data* stored in the JSON file, this is the
correct way to check it.
On the other hand, if you don't care about the data, but you want to
detect changes to whitespace, blank lines, or other changes that make no
difference to the JSON data, then there is no need to care that this is
JSON data. Just treat it as text, and use the difflib library.
