Extract email from people picker in another column

[RADical6142]

Hello, I have two columns in a SPO list. One has a people picker for the data type and the other is a text column. I am trying to autoupdate the text column with the email address of the person selected from the people picker column. Is this possible without the use of Power Apps form customization?

@RADical6142 If you just want "display" value in list view, you can use JSON formatting on column like: 

{
   "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
   "elmType": "div",
   "txtContent": "[$PersonGroupCol.email]"
}

Output: 

If you want to store the value in column & use it somewhere else, you can create a power automate flow to update the Email address field based on the Person or Group field.

Check my answer given in this thread where I have explained same scenario in detail: Get Email from user and enter into SharePoint list field
