使用python对excle和json互相转换

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")
