Find and replace with exclusion

[comlitbeta]

Hello
I have a document that is a mess.

A part of it is that there is a lot of line break in the middle of what is suppose to be full sentences.
is there a way to find and replace every line break that isn’t preceded by a period

example:

Alpha bravo charlie
delta.

Echo.

Foxtrot golf hotel
india.

Here i would want to remove the line break after charlie and india but not the others.

Thanks in advance.

1. make sure you clearly identify line breaks and paragraph breaks : Formatting Marks
2. using regular expressions, replace all ([^\.])\n with $1
   
   

And for background info and variations, see many discussions like this one :

Find and replace double paragraph breaks & make paragraphs continuous

See this question: writer:remove paragraph breaks at end of line containing characters

[^\."]

from previously linked regular expressions, you have :

note: . is a special character in regex, so
