JavaScript 技术篇-JSON字符串在线快速格式化查看实例演示，json.cn网址格式化json字符串

下面这个 json 串，默认是连着的一长串，我们不容易看出其结构。

{"data":{"list_head":{"rows":[{"status":"0","isOptimized":false,"values":{"pk_group":{"value":"0001E210000000002S99"},"pk_name":{"value":"33"},"creator":{"display":"zhangypm","value":"1002E210000000005084"},"modifiedtime":{},"pk_os":{"value":"1002Z9100000000250DQ"},"modifier":{},"pk_code":{"value":"33"},"pseudocolumn":{},"creationtime":{"value":"2020-06-09 20:32:01"},"dr":{"value":"0"},"pk_org":{"value":"0001E210000000002S99"},"ts":{}}},{"status":"0","isOptimized":false,"values":{"pk_group":{"value":"0001E210000000002S99"},"pk_name":{"value":"44"},"creator":{"display":"zhangypm","value":"1002E210000000005084"},"modifiedtime":{},"pk_os":{"value":"1002Z9100000000250DR"},"modifier":{},"pk_code":{"value":"44"},"pseudocolumn":{},"creationtime":{"value":"2020-06-10 14:07:36"},"dr":{"value":"0"},"pk_org":{"value":"0001E210000000002S99"},"ts":{}}}],"areacode":"list_head"}},"success":true}

直接登录 http://json.cn/ 地址，左边把 json 串粘上，可以看到右边已经格式化好了。
