Wanted to create a List with team details from the user related information available in MS 365

[AmithKumar]

HI I am developing a site for my team using SharePoint Online (MS 365) and in which a Team Details List needed to be created which will show various details about a team member and most of the required information such as full name as per HR record, First Name, Last Name, email address, phone number, employee ID etc etc...I know if I make a column type into Person or Group and then select my SharePoint group (member, visitor owner or custom made) and then I can find their data. And I can replicate each column same column type but with different user details. But the challenge is these columns are not connected to each other. For e.g. if I add user by picking from the Group data in to First Name field, it doesnt automatically fill the rest of the column with remaining information about that person. i.e. if I pick Forename, his Last name, phone number, employee id etc etc should be populated in the other columns. How can I achieve this?

Have you looked into creating a Flow to populate the other fields?  It should be fairly simple, but you'll want to watch out for creating an update loop.

@nulloremptyI know i can use Flow which is much easier but Power Automation is yet to enable for us...but can't wait to create this list until then.

Add a text field to your list, then set the JSON formatting as follows:

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

I created a list, then added a People/Group column titled person.
After that, I created a text column titled personEmail and set the JSON formatting to what's displayed above.
