SharePoint Online: Copy Values from One Column to Another using PowerShell

Requirement: Copy values from one column to another column in SharePoint Online list.

PowerShell to Copy List Column Value in SharePoint Online

To copy values between columns in the same list, use this PnP PowerShell script:

$SiteURL = ""
$ListName = "Projects"
$SourceColumn = "Project_x0020_Name" #Internal Name of the Fields
$DestinationColumn = "ProjectName"

#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -UseWebLogin
#Get all items from List
$ListItems = Get-PnPListItem -List $Listname

#Copy Values from one column to another
ForEach ($Item in $ListItems) 
    Set-PnPListItem -List $Listname -Identity $Item.Id -Values @{$DestinationColumn = $Item[$SourceColumn]}

For field types like single lines of text, choice this script works fine. However, for other field types such as hyperlink, person or group, etc. we’ve to do some more work.
