使用excel对json数据单一属性值进行提取

今天遇到了json数据文件，需要对单一属性值进行提取，可以使用excel的mid函数以及find函数进行

比如：

{"data":{"body":{"data":{"system_ename":"ttye","headimg":"http://imgser.yaotv.tvm.cn/rts/2016/1222/8c6a3d2f3d9592161a7675abd1dd1b44.jpg/64","yyyappid":"","city":"鍞愬北甯�","prize_img":"http://q-cdn.mtq.tvm.cn/ftp/hb.png","topicname":"ttye_danmu","msgtimefen":201702240303000,"type":"hongbao","message_score":56,"content":"鎽囧埌1涓彁鐜伴敠鍥�","danmutype":"app","prize_url":"","province":"娌冲寳鐪�","nickname":"闆姳","entrance":"app","timestamp":1487876600568,"tvmid":"wxh5857ac55ef488f7f2b2920cb"

如果要提取tvmid的值，则使用函数mid（A1，find（"tvmid"，A1,1）+8,27）进行提取，具体的使用方法可自行百度
