I have this:

^.*(?!.*[^\S])(?=.*[a-zA-Z]).*$

And this does not match if the string has a space at the end.

I'm trying to make it so that it matches only if the string does not have a space anywhere, not just at the end. How can I do this?

How about simply:

^[\S]+$

Simplest expression to match a non-empty string with no blank characters:

^\S+$
