docs: The function read_json accepts three input types:
              1. filepath (string-like)
              2. file-like object (e.g. open file object, StringIO)
              3. JSON string
  
          This method turns (1) into (2) to simplify the rest of the processing.
          It returns input types (2) and (3) unchanged.
