Hi.  
I have packet data and type is hexadecimal.

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/b/6/b6baaa1dec313a2f1196c7681c3df1949bb68f70.png)  
when I change to json, it looks like 01:00:00:80:00:00:00:01:00:00:00 in kibana's discover.

I want to change this hexadecimal type to binary in kibana.  
do I need to change at the logstash configuration file ? or can I change at the kibana scripted field?

I searched a lot but I have no idea how can I change the type.

There are clear [rules](https://www.rapidtables.com/convert/number/hex-to-binary.html) on how to do it.  
Better do this before loading into the index, if possible.

hello. thank you for replying.

I have many hexadecimal data in packet, then how can I change all the hexadecimal type to binary before loading into the index?
