Python读取Json字典写入Excel表格的方法

需求:

因需要将一json文件中大量的信息填入一固定格式的Excel表格,单纯的复制粘贴肯定也能完成,但是想偷懒一下,于是借助Python解决问题。

环境:

Windows7 +Python2.7 +Xlwt

具体分析:

原始文件为json列表,列表中有多个字典,生成Excel文件需要将列表中的字典的键值按键对应排列,也就是说,所有为“XX”的键对应的值写在一列,且每个字典中的不同键的键值保证在同一行。 
解决思路是,读取json文件,然后遍历字典的键和值,读完第一个字典并写入Excel后换行,读取第二个字典。

代码:

# -*- coding: utf-8 -*-
import xlwt
import json

# 创建excel工作表
workbook = xlwt.Workbook(encoding='utf-8')
worksheet = workbook.add_sheet('sheet1')

# 设置表头
worksheet.write(0, 0, label='NAME')
worksheet.write(0, 1, label='LEN')
worksheet.write(0, 2, label='ID')
worksheet.write(0, 3, label='OTHER')


# 读取json文件
with open('test.json', 'r') as f:
 data = json.load(f)

# 将json字典写入excel
# 变量用来循环时控制写入单元格,感觉有更好的表达方式
val1 = 1
val2 = 1
val3 = 1
val4 = 1
for list_item in data:
 for key, value in list_item.items():
  if key == "NAME":
   worksheet.write(val1, 0, value)
   val1 += 1
  elif key == "LEN":
   worksheet.write(val2, 1, value)
   val2 += 1
  elif key == "ID":
   worksheet.write(val3, 2, value)
   val3 += 1
  elif key == "OTHER":
   worksheet.write(val4, 3, value)
   val4 += 1
  else:
   pass

# 保存
workbook.save('OK.xls')

辅助文件:

test.json

[
  {
   "OTHER": "code",
   "NAME": "whc",
   "LEN": 100,
   "ID": "01-0001"
  },
  {
   "OTHER": "house",
   "NAME": "ikd",
   "LEN": 200,
   "ID": "01-0002"
  },
  {
   "OTHER": "thank",
   "NAME": "qxf",
   "LEN": 300,
   "ID": "01-0003"
  },
  {
   "OTHER": "music",
   "NAME": "kmn",
   "LEN": 400,
   "ID": "01-0004"
  },
  {
   "OTHER": "big",
   "NAME": "vbf",
   "LEN": 500,
   "ID": "01-0005"
  },
  {
   "OTHER": "over",
   "NAME": "wsr",
   "LEN": 600,
   "ID": "01-0006"
  }
]

结果示例:

ok.xls
