hi i am trying to import a json file on iterate over it so that certain values are inserted into a db. In this case i need artifactid, version insertred. The json file has a list so i would have multiple inserts. I think i am on the right track , any help would be greatly appreciated. At the moment this is the error i am getting for v in parsed['groupId'].values(): TypeError: list indices must be integers or slices, not str

Answer 1

'parsed' is a list and not a dict. It contains dicts. Each dict contains a field named 'groupId'. So your code should look like.

Upload "JSON/Java.json" to a public location if the code below does not work for you.

for entry in parsed:
    # entry is a dict - do something with it
