I mean, how can I get from this:

tony:
av petit
mary:
2345678
freddy:
piso23
james:
@mail

a result like this:

tony:av petit
mary:2345678
freddy:piso23
james:@mail

I might try a regular expression (search mode!) replacement:

Search for: (?-s)(.+)\R(.+)

and Replace with: \1\2

Hello, @kikenetxy-giga, and All,

Elementary !

• Open The Replace dialoag ( Ctrl + H )

• SEARCH :\R

• REPLACE :

• Tick the Wrap around option, if necessary

• Select the Regular expression search mode

• Click once on the Replace All button or several times on the Replace button

Notes :

• The \R regex syntax search any kind of Line-Break ( \r\n in Windows files, \n in Unix files and \r in Mac files )

• So the search regex looks for a colon :, ending a line

Best Regards,
