将csv导出json格式

将csv导出json格式

import os,csv,json
cf = open('D:\OneDrive\\Tech\\Script\\Powershell_Script\\Uxin_work\\VM-Export2012\\VMs.csv','r')
for x in csv.DictReader(cf):
      d = json.dumps(x,indent=6,separators=(',',':'), ensure_ascii=False)   #,sort_keys=True
        print d
cf.close()

将csv导出json格式(适用于python manage.py loaddata导入的json格式化文件）

import os,csv,json
#cf = open('vms.csv','r')
cf = open('D:\OneDrive\\Tech\\Script\\Powershell_Script\\Uxin_work\\VM-Export2012\\VMs.csv','r')
cf_count = len(cf.readlines())
cf.seek(0)
if(os.path.exists('vms22.json')):
    os.remove('vms22.json')
c2 = open('vms22.json','a')
cf.read(3) #去掉文本开头几个文件编码显示字符

c2.write('[' + '\n' + '{' + '\n')
n=1
for x in csv.DictReader(cf):
      d = json.dumps(x,indent=6,separators=(',',':'), ensure_ascii=False)   #indent=6缩进6个字符 separators=(',',':')去除,和:后面的空字符串等  sort_keys=True按key排序  ensure_ascii=False解决中文乱码问题
      d2 = '  "fields": ' + d.replace('PSComputerName\\','PSComputerName') + ',' + '\n' + '  "model": "sinfors.hvvms",' + '\n' + '  "pk": ' + str(n) + '\n'

      c2.write(d2)
      if n < cf_count-1:
          c2.write('},' + '\n' + '{' + '\n')
      else:
          c2.write('}' + '\n' + ']' + '\n')
      n=n+1
cf.close()
c2.close()
