I'm totally new to kibana.

I have the current problem, I created a visualisation chart which is splitting rows based on the UUID. In this Index, I unfortunately don't have the related organisation name to the UUID.

My question now is can I map the UUIDs to a specific String value using "advanced JSON input"? So i see the organisation names instead of the UUIDs.

Eg.  
if organisation\_uuid == "1001" {  
organisation\_uuid = "Organisation 1"  
} else if organisation\_uuid == "1002" {  
organisation\_uuid = "Organisation 2"  
} else if ...

Thank you in advance for helping a newbie 🙂

hi @officer_snickers

this kind of transformation of one value to another (e.g. `1001` -\> `Organization 1`) is easiest to do with a scripted-field: [https://www.elastic.co/guide/en/kibana/current/scripted-fields.html](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html) Basically, you would create a new scripted field that uses a little script to generate the value.

It's a feature of a Kibana index pattern. You would write a script in the painless-language that does this transformation.
