As the .json files you are reading are encoded in UTF-8, you'll need to set your Code Page setting in the Input Data tool appropriately. This should get you moving!
Since your input is being read as JSON directly, you likely won't need the JSON Parse tool (if you were reading your .json file in as a raw text file, this is when you would need something like that). Once you've got the data in you can begin to manipulate it. I found a good post that illustrates how to take the data and convert it into a more tabular format with an example if you're interested as well!
