Thanks for answer. Your example woks with the word TextPad.

I need to use it with any words in a list of about 300 000 Words.

So I search for [a-z][A-Z] and then tried to replace with [a-z]\n[A-Z], but this doesnâ€™t work ??

So you dont know the specific words.
What will identify the words that need breaking?
And where will they break... 3,4,5 or n th letter?
Tough nut to crack...I've been sitting here last 15 mins figuring this may be some kind of joke??

Sorry, this is not a joke.

IÂ´ve got a list of words. Some of them are put together like TrainStation, but this should be two different words.

The words will be identified with the combination of Uppercase after Lowercase. This works well with the search for [a-z][A-Z].

For these words IÂ´ll need a break between the Lowercase and the Uppercase. In our Example Textpad finds with regular expressions and the search for [a-z][A-Z] the Word TrainStation, and this word should be broken like

Train
Station

Using [a-z]\n[A-Z] in the field replace, produces

Trai[a-z]
[A-Z]tation
