I have a SharePoint list with a "Responsible" column, its column type is "Single line of text". Now I want to change column type from "Single line of text" to "People", do you what is the best way to do it?
I know the below workaround but it's too time consuming for a list with more than 5000 items:
1. Create a new "People" column and move it next to the "Text" column
