Help me please.

With which regex have you come up so far and why does it not work? Replacing [ ]([A-Z]) with {b}\1 seems like a trivial solution – knittl

You can do that using a lookahead, it is used to ensure that a specific text follows the match:

\s(?=[A-Z])

All spaces followed by a capital letter will be matched.

  • \s: matches any whitespace character.
  • (?=): positive lookahead.
  • [A-Z]: matches a single character in the range between A and Z.

You can test it here.
