I have a sheet in which data is pasted (or imported) from another source.
One column (Requester) has been set up using the Contact list column type, as we have automations based on the status in another column changing or a row comment. The team entering the data pastes the data, then manually changes the Requester field for each row over to a Contact instead.
I'd like to set up an automation so the team who is responsible for managing the data entry gets a notification when a row has a plain text value entered for the name rather than it being properly associated to a Contact. What is the best way to do that?
