You can use a [split filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html) to divide an array into multiple events. You can move fields to the top level using [this](https://discuss.elastic.co/t/how-to-dynamically-move-nested-key-value-to-root-level/180006/2).

Thank for your response.  
To use split, objects are comma separated

> results: [  
> { result ... },  
> { result ... },  
> { result ... },  
> ...  
> ]

I don't have this for my values

> results: [  
> { result ... }  
> { result ... }  
> { result ... }  
> ...  
> ]

If it is a string rather than an object you could [scan for a regexp](https://discuss.elastic.co/t/parsing-ip-address-coming-at-random-places-inside-logs/259177/5).

Thank,  
But I have a big strings. So complex to write regex for this!
