What program can delete N lines before a character/word and/or after?

Question

Notepad++

Hello.
The array of strings is large, about 20 thousand. I didn't find regular notepad++ for strings.
There is text:
111
222
333
AAA
444
555
666
You need to delete 1 line before and 2 after "AAA".
What editor can do that? Excel is not offered.
