I have the date as YYYY-MM-DD in kibana, I want to convert this one to date, so that i can use it in Visualisation.

Hi,

You can use runtime fields to do your mapping. or scripted fields if you are on a version older than 7.11 of elasticstack.

Here are our es docs - [Runtime fields | Elasticsearch Guide [master] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/master/runtime.html)  
[Getting started with runtime fields, Elastic’s implementation of schema on read | Elastic Blog](https://www.elastic.co/blog/getting-started-with-elasticsearch-runtime-fields)

You can do it using UI in kibana -

Thanks
