SharePoint Online: PowerShell to Read List Items
You can read SharePoint Online list with PowerShell in these three simple steps:

Step 1: Connect to SharePoint Online Site
To start with, we need the connection context to the SharePoint Online site.  

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
   
#Variables for Processing
$SiteUrl = "https://crescent.sharepoint.com/"
  
#Get Credentials to connect
$Cred = Get-Credential

#Setup the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)

Step 2: Get List Items from SharePoint Online List
Once the connection is established, we can read or update any object from the SharePoint Online site.

#List Name Variable
$ListName = "Projects"
 
#Get the list
$List = $Ctx.Web.Lists.GetByTitle($ListName)
 
#Read All Items from the list
$ListItems = $List.GetItems([Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery())
$Ctx.Load($ListItems)
$Ctx.ExecuteQuery()
Write-host "Total Number of Items Found in the List:"$ListItems.Count

Step 3: Loop through List Items Collection to Read List Items
Once we get the list items collection, we can read list items by iterating through each list item. 

#Iterate through List Items
ForEach($Item in $ListItems)
{
    #sharepoint online powershell read list items 
    Write-Host ("List Item ID:{0} - Title:{1}" -f $Item["ID"], $Item["Title"])
}

{
    #sharepoint online powershell read list items 
    Write-Host ("List Item ID:{0} - Title:{1}" -f $Item["ID"], $Item["Title"])
}
