Find and replace to add new line mark on iPad

I have a long list of words divided by commas in PAGES on my iPad. I need to remove the commas and get each word on its own line. I don’t have MS Word which can do this I think. I would love to do a FIND and REPLACE of the comma for the NEW LINE MARK, but nothing works. It won’t work in PAGES, NUMBERS or GOOGLE DRIVE.

Is there,any way to,do this in an iPad?
