使用python对excle和json互相转换的示例

python 版本：2.7
只是读取excel的话可以直接使用xlrd
1、excle to json
代码如下
# -*-coding:utf8 -*-
import xlrd
from collections import OrderedDict
import json
import codecs
file_name=raw_input('请输入要转换的excle文件路径:')
wb = xlrd.open_workbook(file_name)
dict_list = []
sh = wb.sheet_by_index(0)
title = sh.row_values(0)
for rownum in range(1, sh.nrows):
rowvalue = sh.row_values(rownum)
single = OrderedDict()
for colnum in range(0, len(rowvalue)):
print(title[colnum], rowvalue[colnum])
single[title[colnum]] = rowvalue[colnum]
dict_list.append(single)
j = json.dumps(dict_list)
with codecs.open(file_name[:-5]'.json',"w","utf-8") as f:
f.write(j)
2、json to excle
代码如下
注意：标题会写在最后一行，主要针对字段不同的json数据。
import json
import os
from openpyxl import Workbook
wb = Workbook()
ws = wb.active
cols = []
def json2excel(jsfile, excfile):
# 读取json数据
a = 1
if os.path.exists(jsfile):
with open(jsfile, 'r') as fp:
while True:
line = fp.readline()
if not line:
break
jsdata = json.loads(line)
for k in jsdata.keys():
if k not in cols:
cols.append(k)
rowdata = []
for col in cols:
rowdata.append(jsdata.get(col))
print '正在写入的行数：'a
ws.append(rowdata) # 写行
a += 1
ws.append(cols) # 标题
print('保存中')
wb.save(excfile) # 保存
if __name__ == '__main__':
import sys
if len(sys.argv) == 3:
jsfile = sys.argv[1]
excfile = sys.argv[2]
json2excel(jsfile, excfile)
else:
print("Usage: python writeExc.py xx.json xx.xlsx")
