Hi guys , can you help me with writing an action ? After using the "Case Conversion" on all fields , i'm left with a bunch of random Artists & Album Artists that now read \> Brian MCFadden , Norris MCWhirter etc ![:unsure:](https://community.mp3tag.de/uploads/default/original/1X/cfaeba84fe6704387c5b34dfdd8172bd51b6f533.gif ":unsure:") - But i want it to read Brian McFadden or Norris McWhirter I'm guessing that i need to do a 'replace with regular expression' on the %artist% and %album Artist% fields , but i don't know what code to use for the rest ? can you help ? many thanks Lee ---

I am not sure what you mean by "the rest" - the action is the same for any field where you find that kind of data. ---

Wow that was a quick reply ! Thanks Ohrenkino , your suggestion worked great , and did exactly what i needed . the only problem is that it also changed artists like _The Boomfunk MC's_ and _Young MC_ to The _Boomfunk Mc's_ and _Young Mc_ - is there any way i can avoid this ? Lee ---

Probably not. These are those special cases of the illogical everyday language ... BUT: if you know that these are the only exceptions, you could add another replace action that replaces Mc's with MC's. And the "MC" problem: I think that this is also a case for some post-treatment when the majority of cases has been dealt with. Add an action of the type "Replace with regular expression" Search string: Mc$ Replace string: MC This looks for the string Mc at the end of a field and replaces it. If the MC is not the last word in a field, you can use a simple replace again Search string: _Mc_ Replace string: _MC_ The underscore represents a space character, use that instead, the underscore was only used for clarification purposes. ---

In cases like this, where not all the changes are needed, you can do this: 1] search [filter] for "MC" 2] look at the pre-selected files 3] remove unwanted cases [that are not to be changed] 4] run the automatic replacement process and then 5] repeat the the search process 6] repeat the manual and automatic process and the 7] check out all changed files So basically, you should not run the automatic process on all of the files; because executing it on a pre-selected file gives less room for a mistake Depending on how many files you have, this can take a long time. But only in this way you will be certain, that you are not making unnecessary changes ---
