(?-s)^\u+).+\K\R(?!\u))(?!ANSWER)

I don’t know how to express gratitude on the internet. But BIG THANKS. YOU SAVED ME A LOT OF TIME.

Really. THANK YOU.

You misunderstood on one (the … wasn’t part of the expression: it wasn’t red), and I had a couple of typos (accidentally said \h+ instead of \u+).

I guess I should have spelled it all out, and should have tried it before posting.

And if any of your choices are 3 or more lines long, just re-run the regex until it doesn’t make any more changes.

(?!\h+))(?!ANSWER:)

Sorry I’m new to this. English is not my mother tongue.

I understood this?:

Find: (?-s)^\u+..+\K\R(?!\h+))(?!ANSWER:))
Replace: a single space
Search mode: Regular expression

Obviously I did something wrong because it says Invalid Regular Expression.

I managed to erase some parenthesis but the result was that B options and C options dissapeared or merged in one line… I’m a complete disaster. but i managed to undo actions. Everything is fine, answers are back, but I can’t put them in one line yet.

did you know how to do the same, but for the Answers?

In the regex that @Alan-Kilborn showed, the \d+\. at the beginning means “one or more digits followed by a literal dot character”.

For requiring it to be one or more letters then an end-parentheses like your answers are, replace that portion of the regex with a regex that means “one or more uppercase letters followed by a literal parentheses”: \u+\) …

Further, the (?!A\)) says “stop the match once you hit a literal A)” … So the equivalent for the answer would be "stop the match once you hit a different capital(s)-then-paren, and stop if you come across ANSWER: -> (?!\h+\))(?!ANSWER:)

Those tweaks to the original will work for your new

Sorry to bother you again… did you know how to do the same, but for the Answers?

I mean… I have this format:

A) XXXXXXXXX
XXXXXX
B)XXXXXXXX
C)XXXXXXXX
D)XXXXXX
XXXXXXXX

I want A and B or whatever answers in the exam to be in 1 line too, like this:

A)XXXXXX
B)XXXXX
C)XXXXXXXXX
D)XXXXXXXX
