you received an error. json.decoder.JSONDecodeError: Extra data error. The reason is that the load method can only handle a single JSON object. And it seems that your file contains more than one JSON object. Use the following code to parse a JSON file with multiple objects
jsonData = []
with open('a.json') as f: jsonData = [json.loads(line) for line in f]
print(jsonData)import json lines = [] with open('C:\\Users\\Owner\\Desktop\\jsondata.txt','r') as file: for line in file: lines.append(json.loads(line)) print(lines)
