See  
FAQ: [How to change upper/lower case of tag fields or filenames?](https://community.mp3tag.de/t/actions-and-batch-operations/967/3)

and refer to to  
FAQ: [How to replace the string “xyz” in tag-fields or filenames?](https://community.mp3tag.de/t/actions-and-batch-operations/967/4)  
for other replacements (e.g., Tv to TV). Make sure you have the option only as whole word enabled, for all string replacements where it should not replace a substring inside a word.

You can check this post for an action for upper-case roman numbers
