How do I display the ID using JSON formatting?

Hi dlprentice

Can you elaborate on how you did this. It does not work for me. Can you share how you added it to your JSON.

Thanks

dlprentice emersonbruce Yes, it is a limitation of SharePoint list form JSON formatting.

You can read more information about it at: Can ID column be displayed when configuring a list form header using JSON? 

Creating a calculated column based on item ID (like =[ID]) and using it in list form JSON formatting by referring to internal name of SharePoint calculated column is a workaround which might work you for sometimes but it is not officially supported by the Microsoft:

You cannot reference the ID of a row for a newly inserted row. The ID does not yet exist when the calculation is performed.
