Elastic Stack Logstash

Hi, I'm new with ELK. Just want to ask, how to remove "[" on the logstash?

[{"uuid": "8153990955613214174559836954673410970", "label": ["Phone", "Laptop", "Pc", "Computer", "Iphone", "Mobile Phone", "Electronics", "Cell Phone"]

Example, I want to remove the "[" bracket using mutate in logstash, it is possible?

Hello Mario,

You can use the grok filter for example.

This could be your pattern: \[%{GREEDYDATA:json}\]

It creates a field called json containing everything between the brackets.
