【Python】EXCEL转Json
在⽹上查阅了好⼏个EXCEL转Json的代码，有的是仅⽀持⼀个层级的Json（这个就不⽀持多层级的json），有的太过复杂看的不是很懂，所以就⾃⼰写了⼀个⽬前符合⾃⼰使⽤的代码。我先讲下实现的⽅式。
如果遇到⼀个如下的json格式，我该怎么存到excel⽅便读取出来呢？
{
"name": "haha",
"value": 12,
"floor_area": 43.5,
"categories": [
{
"id": 1,
"extra_property": "xixi",
"renovation_type": [
1,
2
],
"subcategories": [
{
"subcategory_id": 1,
"subcategory_value": 2
}
]
}
]
}
这是个多维json，存在excel中不是很好存放，读取出来也得花点⼼思，毕竟你不知道后期⼜会有什么格式的json出现。为了应对千奇百怪的json格式，我想到如下⽅式
上图中特别标注的，可以划分为三个部分，以下对这三个部分进⾏讲解。
区域⼀（功能校验区域）：
user：登陆的⽤户或操作的⽤户
real_code：预计接⼝执⾏操作后需要返回的code值，如200、401等
real_message：预计接⼝执⾏操作后需要返回的message，如“请求成功‘、”⽆操作权限“等
区域⼆（参数类型区域）：
传递参数的类型⽆外乎这⼏种：int、str、float、boolean。同样我们需要告诉代码这个参数是什么类型的参数，以免传递数据的时候发⽣参数类型错误。在代码中我做了处理，可以识别常⽤的四种类型（不区分⼤⼩写）。
区域三（参数区域）：
如果是数组类型的数据，⽤"[]"来标记，不同的数据存储在不同的单元格中，如：
看到图的时候你会问：为什么sheet⾥⾯会有参数的名称？
我们可以看出“categories”是个哈希，底下还存在不同的参数。为了知道哪些参数是在“categories”下的，我们可以⽤⼀张sheet去存储“categories”参，这样我们可以通过代码⽅便去到。
有可能“categories”存在多组数据，所以我们需要⽤"[]"来告知代码。要读取那些数据，我们可以存储⾏号，不同的⾏号可以⽤顿号分隔

说到这，我们来讲讲她的缺点：
1、如果存在多张表的嵌套，代码执⾏的时间⽐较长
