I've tried following the instructions in this post: How to separate or split strings that are written in one word? But it doesn't seem to work. Mp3tag doesn't like the expression (\1) (\u): I get the message: "Invalid back reference: specified capturing group does not exist. The error occurred whil…

The expression should work for most of the titles. Select the files in the files list. Create an action of the type "Format value" or open the function Convert>Tag-Tag Select as field: TITLE Enter as Format string: $regexp(%title%,(\l)(\u),$1 $2) Apply the function with OK.

[image] Len44: (\1) (\u): You have to use the letter l (small L) and not the number 1. The same applies to your choice of the pipe symbol. This regular expression works as described $regexp('TagsLikeThese ',(\w|,)(?=\u),$1 $2) and this one also: $regexp('TagsLikeThese ',(\l)(\u),$1 $2) …

OK. Thanks. Of course, the u (uppercase) must be balanced by an l (lowercase). I've made the edit, the script parses, but it made no changes. This is what I'm trying to do: I have, for example, a song TITLE: "DoItAgainVer2". I want it to be: "Do It Again Ver 2". (I understand the digit might be a …

You have to show, preferably with a screendump, what you are doing. $regexp('DoItAgainVer2',(\l)(\u),$1 $2) leads to Do It Again Ver2

Hi - Yes, You've solved my problem brilliantly. And I see where I was wrong. Unfortunately, I've haven't describe the task very well. I want to change multiple files like that. [mp3tagscreen] You can probably see what I want. Thanks again. L

It worked like a charm. Thank you so much! L

Is there as tutorial here that will help me learn how to write formulas/expressions like "$regexp(%title%,(\l)(\u),$1 $2)"? For example, I am familiar with a certain amount of programming, so I get the use of %%, but where are the variables $1 and $2 defined (if they are variables)? And the syntax…

See e.g. the help (press F1) [image] Replace with Regular Expression – Mp3tag Documentation Documentation on the Replace with Regular Expression action type that can be performed as Quick Action or as reusable workflow from Action Groups. Mp3tag is the universal Tag Editor. …

This script works really well whenever you're using it in the tag. To tag format. But when you try to use this same exact logic and an action, it does not work correctly. What's the work around to get it to work in an action?

[image] Canuname: What's the work around to get it to work in an action? It works in any action that allows a generating format string. The most versatile in this case would be an action of the type "Format value".
