Check if value in field exists in a list

Hi all!

Imagine you are scouting for a new apartment in a new town, and fill a Notion DB with the details of apartments you are interested in: Owner name, Address, etc.

But! Not everyone in this new town is nice - some of them are horrible flat owners and you wish to avoid them. You are lucky enough to have a list of bad owners which you have, conveniently, also kept in Notion.

Could you build into your apartment database some function that will turn on if you fill in a name that exists in the naughty list?


Should look something like this:

Evil name list: Bill, Bob, Karen

Notion DB:

Name Address IsEvil?
Phil 7 Short st -
Joe 12 Short st -
Jane 4th avenue -
Karen 27 Short st XXX

You can do a simple check using a Notion formula.

Create a new Notion property as formula and add the following.

if(prop("Name") == "Karen" or prop("Name") == "Joe", "run", "stay")

That will check the names and will show "run" for Karen or Joe and stay for everyone else.

You can extend the or in the formula with all the bad owners.

Hope that helps.

Awesome solution, thanks!

Is there a way you know of to modify this in case that list includes ten names? Or would it have to be a long list of Or statements?

You have to add the ten names (or the needed ones) to the formula. If you consider the question solved, please select the answer to mark it. :)

Glad to help!

You're welcome :)

Notion formulas run per row and that is why you need to include everything, so it checks the Name row itself to see if one of the names you included is there.
