I can not separate words like this: In case I have CPFConsole , I wanted to separate to CPF and console.

The code I have separates like this: ([A-Z][a-z]+)|([a-z]{0,})|([A-Z]{2,})

But this code separates this way: CPFC and onsele .

If the entry is CPFConsole and you want only CPF, you can use this expression:

(^[a-zA-Z]{3})+

This expression takes the first three letters of your word.

See working at OnlineRegex .

Edit: According to your comment, if I understand correctly, the expression that JuniorNunes has put up works:

^([A-Z]+)([A-Z]{1}[a-z]+)

Following the criteria we can set up REGEX like this:

pattern : /([A-Za-z])([A-Z][a-z])/g
replace : $1 $2

See working at REGEX101 .

([A-Za-z]) - Group 1, search for upper or lower case.
([A-Z][a-z]) - Group 2, search for 1 uppercase letter, followed by 1 lower case letter.

If you need to separate by counting the letters:

([A-Za-z]{3})([a-zA-z]*)

It will separate into two groups.

Full match 0-10 CPFConsole

Group 1. 0-3 CPF

Group 2. 3-10 Console

If you need something more specific:

(CPF)(Console)
