Trying to read data returned from parse_json() (aka JSON.parse(), I believe they do the same thing).

So my string of data I am parsing is a validated json string that starts and ends with curly braces {}. When I check JSONParseResult that is returned, JSONParseResult.error is OK. When I look at JSONParseResult.result, typeof tells me it is a string and this is where I am having trouble. I want it to be an array, or Dicitonary, or JSON object? So I can read the data. Otherwise I have to parse this result string myself which I will do if I have to but it seems like json_parse should be somewhat more helpful in the regard, the whole point of using it in fact. I really feel like I am missing something because searching Google is not producing an answer.

Which Godot version are you using?

Also, can you post the JSON string in question here? Or, better, upload a minimal reproduction project so other people can try to troubleshoot this.

You should be getting a JSONParseResult. Which in your case would store a Dictionary in "result".

https://docs.godotengine.org/en/stable/classes/class_jsonparseresult.html#class-jsonparseresult

Can you post some code of how your are loading the Json? There is not enough info to help.

OK, thank you for the Dictionary hint. So apparently JSON.parse returns a JSONParseResult. After checking no errors, I had to then call get_result() method of JSONParseResult. This returned a string. Then I had to call parse_json() passing this string as a parameter. This is what finally resulted in the Dictionary variant I needed. Yay! Code below:

data string passed (downloaded from cloud):  
str_card_dict = "{\"id\":0,\"x\":388.114319,\"y\":285.681793,\"to_lines\": [{\"0\":\"N\"},{\"1\":\"N\"},{\"2\":\"N\"},{\"3\":\"N\"},{\"4\":\"N\"},{\"5\":\"N\"},{\"6\":\"N\"},{\"7\":\"N\"}],\"from_lines\": [{\"0\":\"[]\"},{\"1\":\"[]\"},{\"2\":\"[]\"},{\"3\":\"[]\"},{\"4\":\"[]\"},{\"5\":\"[]\"},{\"6\":\"[]\"},{\"7\":\"[]\"}]}"
					
					var result_json = JSON.parse(str_card_dict)   # data string from cloud to be converted 
					#var result = {}
					if result_json.error != OK: # If parse has errors
						print("Error: ", result_json.error)
						print("Error Line: ", result_json.error_line)
						print("Error String: ", result_json.error_string)
					else:     # If parse OK
						# result_json typeof = JSONParseResult object
						print("result_json of JSON.parse typeof=", typeof(result_json))
						var json_data = result_json.get_result() # should return a Variant of type string
						print("json_data typeof=", typeof(json_data))
						#print(json_data)
						var result_dict = parse_json(json_data)
						print("result_dict typeof =", typeof(result_dict))
						print(result_dict)
						var keys = result_dict.keys()
						print(keys)

That's strange. I'm not sure why you would have to parse the result twice.

If the JSON data that's passed to JSON.parse() has embedded quotes surrounding it, would that explain it?

Raw JSON data is normally not enclosed in quotes.
