rest with same pattern...........

I think this will be multiple steps. I am very new to notepad++ but want to learn more about regex and notepad ++ sorting. Any help would be appreciated.

I have been doing it manually by cutting the "configured list of APs" out and using crtl+alt, then pasting each field while adding commmas . There are more than 2500 Aps so i keep thinking there is a better way.

See https://regex101.com/r/p6SWd6/1 (code below)

Replace

Location Name......................: (.+)
Location description...............: (.+)
Policy tag.........................: (.+)
Site tag...........................: (.+)
RF tag.............................: (.+)
Configured list of APs
(?:.{4}\.*
)*?.{4}\..{4}\..{4}(?=\s*\n)

with

$0,$1,$3,$4,$5

however many times you need
