I tried replace "$" with "" but no luck.
if you need to remove blank lines with regex, find "^\s+$" and replace with ""
I have text:
When I try as you wrote, it says: Unable to find ^\s+$
Find: \nReplace: [EMPTY]
@beigetwin you need to enable Regex find option by clicking the .*] button in the find menu or [opt+cmd+r]/[alt+cltr+r]
