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 xlrdfrom collections import OrderedDictimport jsonimport codecsfile_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 jsonimport osfrom openpyxl import Workbookwb = Workbook()ws = wb.activecols = []def json2excel(jsfile, excfile):# 读取json数据a = 1if os.path.exists(jsfile):with open(jsfile, 'r') as fp:while True:line = fp.readline()if not line:breakjsdata = 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：'aws.append(rowdata) # 写行a += 1ws.append(cols) # 标题print('保存中')wb.save(excfile) # 保存if __name__ == '__main__':import sysif 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")

以上这篇使用python对excle和json互相转换的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持武林站长站。
