下面是一个在文件夹中运行的解决方案，其中有1000个json文件。它将读取所有的json文件，并将f_ID和f_Ctb替换为计数，然后将具有相同文件名的文件写入输出文件夹。

import os
import json

all_files = os.listdir()
json_files = {f: f for f in all_files if f.endswith(".json")}
json_files_keys = list(json_files.keys())
json_files_keys.sort()

OUTPUT_FOLDER = "output"
if not os.path.exists(OUTPUT_FOLDER):
    os.mkdir(OUTPUT_FOLDER)

for file_name in json_files_keys:
    f_read = open(file_name, "r").read()
    data = json.loads(f_read)
    output_data = {}
    count = 1
    for key, val_list in data.items():
        for nest_dict in val_list:
            if "f_ID" in nest_dict:
                nest_dict["f_ID"] = count
            if "f_Ctb" in nest_dict:
                nest_dict["f_Ctb"] = count
            if key in output_data:
                output_data[key].append(nest_dict)
            else:
                output_data[key] = [nest_dict]
        else:
            output_data[key] = val_list
        count += 1
    output_file = open(f"{OUTPUT_FOLDER}/{file_name}", "w")
    output_file.write(json.dumps(output_data))
    output_file.close()
