如何将JSON列标题转换为小写

import json

def convert_keys_to_lowercase(json_data):
    if isinstance(json_data, dict):
        return {k.lower(): convert_keys_to_lowercase(v) for k, v in json_data.items()}
    elif isinstance(json_data, list):
        return [convert_keys_to_lowercase(item) for item in json_data]
    else:
        return json_data

# 示例JSON数据
json_data = {
    "Name": "John",
    "Age": 30,
    "Address": {
        "City": "New York",
        "Country": "USA"
    }
}

# 转换为小写
lowercase_json_data = convert_keys_to_lowercase(json_data)
print(json.dumps(lowercase_json_data, indent=4))

function convertKeysToLowerCase(jsonData) {
    if (typeof jsonData === 'object' && jsonData !== null) {
        if (Array.isArray(jsonData)) {
            return jsonData.map(item => convertKeysToLowerCase(item));
        } else {
            return Object.keys(jsonData).reduce((acc, key) => {
                acc[key.toLowerCase()] = convertKeysToLowerCase(jsonData[key]);
                return acc;
            }, {});
        }
    }
    return jsonData;
}

// 示例JSON数据
const jsonData = {
    "Name": "John",
    "Age": 30,
    "Address": {
        "City": "New York",
        "Country": "USA"
    }
};

// 转换为小写
const lowercaseJsonData = convertKeysToLowerCase(jsonData);
console.log(JSON.stringify(lowercaseJsonData, null, 4));
