I have some logs coming from my S3 bucket. The json in it is not valid since it has some non-standard **"** and **{** characters like below: {“app\_id":"fo","geid":"031fc83e0fea5c1e808857bd2db007d5","etid":"generic","ev":1,"date":"2016-02-01 00:00:00","mt":1454281200.04,"ip":"66.249.78.209","foui":null,"session\_id":null,"member\_id":-1,"is\_buyer":false,"url":"[https://de.fotolia.com/search?k="everglades+national+park"&offset=400","action":"displayed\_contents](https://de.fotolia.com/search?k=%22everglades+national+park%22&offset=400%22,%22action%22:%22displayed_contents)"} I tried with _[jsonlint.com](http://jsonlint.com)_ to find it out. How should I deal with it? ---

Perhaps you can use a mutate filter and its gsub option to clean up this mess? ---
