Remove 8 char, save 4, remove 4, save 4, replace 1 and keep rest of the line

Question

In every line I would like to:

• remove char 1-8 (8)
• save char 9-12 (4)
• remove char 13-16 (4)
• save char 17-20 (4)
• replace char 21 (1) with space
• keep the rest of line

and then do it for every line

I have started with:

^.{8}(.{4}).{4}

Is it possible to in oneline or repeat the pattern...

(I use Notepad++ and TextPad)

Answer 1

This should do the trick. Simply count the characters as you've done and replace with the capture groups and a space.

Find

^.{8}(.{4}).{4}(.{4})(.{1})

Replace (incl. the space after $2)

$1$2
