:D
If it was so simple I would never bother to ask :)

Probably I didn’t explain myself in the correct way.

I have 87 “codeUP” (let’s call it this way) and 87 “codeDOWN”, and they are different. Example:
———-
268951
H1019
———-
268681
HY19001
————

And I am looking for a way to switch their position to have:

———-
H1019
268951
———-
HY19001
268681
————

Without having to go for every line and doing it by hand :)
