You could convert the strings into real document structures, eg. using the `grok` processor in the ingest pipeline [https://www.elastic.co/guide/en/elasticsearch/reference/master/grok-processor.html](https://www.elastic.co/guide/en/elasticsearch/reference/master/grok-processor.html)
A more targeted approach is the JSON preprocessor in Logstash [https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html)

Thank you very much @monfera for suggesting approach.
I am new to logstash. Could you please provide any reference/sample JSON preprocessor example in Logstash which will give expected format to index in elasticsearch.
Thanks.

There are a bunch of examples [here](https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html) and setting up logstash is described [here](https://www.elastic.co/guide/en/logstash/current/setup-logstash.html) and there are various blog posts and tutorials if you search, maybe worth searching or asking in Logstash discuss as it's not really Kibana-specific.
