Change a Character in the genre in multiple files at the same time

It'll great what the program had a function for Change a Character in the genre in multiple files at the same time.

Example: if i change the character "," for "/" in the genre of multiple songs that contain the genre "Electro House, Big Room" so that it stays like this "Electro House/Big Room".

Or multiple characters like "," for " /" (space and /).

Thanks.

Looks like "Replace".
So create an action of the type "Replace" for GENRE,
Search string: ,
Replace string: /
