Sometimes when I make some research, I gather data that should be presented in bullet points, preferably in a single cell (as it is kind of data I would not process in any way in the future). I am looking for a way to make it readable for other people using the spreadsheet (on the screen, as well as when they print the spreadsheet).

I would like to make something like that:

————————————————————
| * bullet point 1 |
| * bullet point 2 |
| * bullet point 3 |
————————————————————

So far the only solution is to edit something presented above in a text editor and then paste it to Excel (as I cannot really make bullet points in a single cell). Is there any better solution?
