Upload data from Monday to form based on unique value

Hello @meytalPeleg,

If you are talking about prefilled forms, currently it’s not possible to do that in monday.com. What you can rather do is the opposite, that is merging form data based on unique values and the Duplicates and Uniques app can help you with that.
Here is an answer with a demo on how to do that. If you need any help with the app, you can write to support@kolaai.com
