I have a log winlog.evend\_data.RuleName : technique\_Id=T2343,techniqueName=asdfdasd

I want to change it to winlog.evend\_data.RuleName : technique\_Id : T4343 , techniquw\_name : asdfdasd

I just need the regular expression for this.  
NOTE: Please don't share useless links be specific .. I don't need generic solutions. And Don't post Gork tutorials videos etc

Try using gsub filter,

```auto
mutate {
    gsub => [
      # replace equals with a colon ":"
      "winlog.evend_data.RuleName", "[=]", ":"
    ]
  }

```

Assumes winlog.evend\_data.RuleName is a field name.
