Convert item details into subitems

Dear All!

Currently a client of mine has a database of companies and contacts in item. However, each company has multiple contacts, for this they have about 200 duplicates in their board.

They would like to store general company details in the item, and the different contact details in subitems. Is there a way to convert the existing data to a new view with subitems?

Also, if they want to enter a new item through a form from a different board, would it be possible for monday to automaticly check for duplicates?

Hello @JakobinaSchlemmer,
Welcome to the community :slight_smile:

Concerning the auto-check for duplicates, you can use the Duplicates and Uniques app for that. When a new item comes in the app, can automatically detect if a duplicate exists either in the same board or in other boards through it’s Cross-Boards functionality.
Here is a demo.

Also, concerning the issue with the duplicate companies, you can use same app to merge each companies data into a single item (not as sub-items though).
Here is a demo of how the merge works.

If you need any help with the app, you can always reach out at support@kolaai.com
