### How to separate or split strings that are written in one word?

You have titles that have no spaces between words (written in one big word) and all words start with a capital letter, e.g., **ThisIsTheTitle** (also referred to as CamelCase). How can Mp3tag separate the individual words and insert a space before every capital letter?

Create a [new action group](https://community.mp3tag.de/t/actions/967/2), e.g., **TagsLikeThese** for the field you wish to edit (the example uses the TITLE field):

Action type: Replace with regular expression  
Field: **TITLE**  
Regular expression: **`(\l)(\u)`**  
Replace matches with: **`$1 $2`**  
**[x]** case-sensitive comparison

or  
Regular expression: **`(\w|,)(?=\u)`**  
Replace matches with: **`$1 $2`**  
**[x]** case-sensitive comparison
