You can use the mutate filter plugin in the Logstash's pipeline. An example of the opposite is given in the following link -\> [https://stackoverflow.com/questions/31947860/replace-all-into-spaces-in-field-logstash](https://stackoverflow.com/questions/31947860/replace-all-into-spaces-in-field-logstash)

I am doing like this but it's not working  
"KRH\_IBAN", "\H\H\D\D\D\D\D\D\D\D\D\D\D\D\D\D\D\D\D\D\D\D",  
"\H\H\D\D \D\D\D\ D\D\D\D\D \D\D\D\D \D\D\D\D \D\D"
