How can I move a cell's second line to the end of the first? (turning it into just one line) For the entire column

A conversion process from pdf has skewed some timecodes I put in a column. The last digit has been misplaced to the second line of every cell.

They should all look like this instead:

But instead of double clicking each cell, going to the end of the first line, then pressing DEL to fix it, is there a better way to apply this to the entire column? There’s around 3000 plus cells and doing it manually like that will kill me.

It does not seem to be this case, but in some instances you can select menu Format - Cells… - Alignment tab, uncheck Wrap text automatically, and OK.

There is a Wrap Text icon in the Formatting toolbar.

Ctrl+H, Find regexp \n and Replace it to empty string

Wow that is elegant. Replacing the line breaks with with nothing thus deleting them. Thank you so much, it worked!
