CSV和JSON格式相互转换

1、为什么要进行CSV与JSON格式之间的转换

  CSV格式常用于一二维数据表示和存储,他是一种纯文本形式存储表格数据的表示方式。JSON也可以表示一二维数据。在网络信息传输中,可能需要统一表示方式,因此,需要在CSV和JSON格式间进行相互转换。

2、代码

  csv转json:

    

 student_csv=[];
student_json=[];
with open("student.csv",mode='r',encoding='ansi')as student_csv_file_name:
    read_object=csv.reader(student_csv_file_name);  #用csv模块自带的函数来完成读写操作
    with open("student_csv转json.json",mode='w',encoding='ansi')as student_json_file_name:
        for i in read_object:
            student_csv.append(i);
        key=student_csv[0];
        for i in range(1,len(student_csv)):
            student_json_temp=[];
            for j in zip(key,student_csv[i]):
                k=":".join(j);
                student_json_temp.append(k);
            student_json.append(student_json_temp);
        json.dump(student_json,student_json_file_name);

 

  
  json转csv:
student_csv=[];
student_json=[];
with open("student.json",mode='r',encoding='ansi')as student_json_file_name:
    with open("student_json转csv.csv",mode='w',encoding='ansi',newline='')as student_csv_file_name:
        read_object=json.load(student_json_file_name);
        write=csv.writer(student_csv_file_name);
        for i in read_object:   #读出来是列表
            ledlist=[];
            templist=[];
            for a in i:
                j=a.split(':');
                ledlist.append(j[0]);
                templist.append(j[1]);
            if len(student_csv)==0:
                student_csv.append(ledlist);
            student_csv.append(templist);
        for i in student_csv:
            write.writerow(i);
