Question

In my current scenario am having an excel with all the metadata and person name. This details I have to upload to Sharepoint 2013 list using JSOM.

Am not sure how to handle people and group column with the name. Ex: name: Mukesh which need to be inserted into the list where as the column type is people and group. Here I don't have any user id/email address/ user name.
