I have a list with blank lines like this:
Apple
Banana
Peach
I want to remove the blank lines in the list so it’s like this:
Apple
Banana
Peach
How do I do that?
I’ve tried using replace(myList; newline; emptystring) and all kinds of variations like that, but when I do that, the output comes out like AppleBananaPeach all in a single line.
Welcome to the Make community!
Looks like you have to replace multiple newlines with a single newline. This only takes a single operation (or no extra operations if you are directly mapping it in a field).
{{ replace(1.myList; "/[\n\r]+/g"; newline) }}
This is because this contains two newlines, one at the end of Apple, and another on the blank line (which is why Banana is yet on another newline):
Apple
Banana

Hey @LaurenK The above solution seems correct but it will not work if you have Multiple nextlines.
For this input It will give

@VinayakUpadhyay You’re my hero! It worked!!! You rock! Thank you so much 
@VinayakUpadhyay I’m super curious - at which step are the empty strings from the line breaks removed?
Have you tried removing the extra line breaks in a single operation/step yet, like I mentioned above?
