Я бы написал сценарий, используя Python, в который встроены функции чтения/записи JSON -.
Дан файл myfile.json
, содержащий объект JSON в OP:
#!/usr/bin/env python # Use the Python interpreter
from json import load, dump # Import the JSON file read and write functions
with open("myfile.json", "r") as file_object: # Open the JSON file for reading
json_data = load(file_object) # Load the data into a dictionary
new_list = [item for item in json_data["list"] if item["name"] != "APP1"] # Make a new list without the item that should be removed
json_data["list"] = new_list # Update the dictionary with the new list
with open("myfile.json", "w") as file_object: # Open the JSON file for writing and truncate it
dump(json_data, file_object) # Write the file back to disk
