将多个json文件从文件夹解压到pandas df中

import os
import pandas as pd
import json

def read_json_file(file_path):
    with open(file_path, 'r') as f:
        data = json.load(f)
    df = pd.DataFrame(data)
    return df

def merge_json_files(folder_path):
    dfs = []
    for file_name in os.listdir(folder_path):
        if file_name.endswith('.json'):
            file_path = os.path.join(folder_path, file_name)
            df = read_json_file(file_path)
            dfs.append(df)
    merged_df = pd.concat(dfs, ignore_index=True)
    return merged_df

folder_path = '文件夹路径'
df = merge_json_files(folder_path)
