Google Sheets – How to Add a New Line in a Cell

Here is what I did.

1. Hit ctrl+f to search, and click the "..." button representing more options

   

2. Typed \s+$ or \n in the find field

3. I left the replace field empty
4. Clicked "Search Using RegEx"
5. Clicked replace

I hope it works for you. Also, you can replace \n with any regex expression and it can be immensely helpful.

You could also use:

="1:14:25"+"0:17:12"
