Bullet at start of arrayjoin

I’m using a rollup with ARRAYJOIN(values,"\n • ")

Which is giving me this result

Item 1
• Item 2
• Item 3

I want this result
• Item 1
• Item 2
• Item 3

How do I create a formula that puts a bullet on first item?

This will kind of do what you’re describing:
"• " & ARRAYJOIN(values,"\n• ")

But it’ll display that first • even if no records were linked - so it’s not the cleanest solution.

ARRAYJOIN isn’t really intended for bullet points. It’s meant to create comma separated lists and the like.

To avoid an extra bullet if there are no records, put the initial bullet in an IF statement:

IF(COUNTA(values) >= 1, "• ") & ARRAYJOIN(values,"\n• ")
