$CSVPath = "Folder Path"
#Get he CSV file contents
$CSVData = Import-CsV -Path $CSVPath
#Connect to site

#Iterate through each Row in the CSV and import data to SharePoint Online List
ForEach ($Row in $CSVData)
{
Write-Host "Adding Contact $($Row.FirstName)"
$NewDate = (Get-Date).tostring("yyyyMMdd")
#$NewDate = [datetime]::parseexact($NewDate,'dd/MM/yyyy HH:mm',$null)
# [datetime]::parseexact($NewDate, 'dd-MMM-yy', $null).ToString('yyyy-MM-dd')
#Add List Items - Map with Internal Names of the Fields!
