Not getting all the documents from SHarePoint Site using Powershell

Copper Contributor

Hello, I am trying to get 95000 documents from sharepoint site and convert it into .csv by SharePoint Online Management Powershell.

I am not able to get all of the files.

Below is my code:

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.dll" 
Add-Type -Path "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.SharePoint.Client.Runtime.dll" 
Add-Type -Path "C:\Program Files\SharePoint Online Management Shell\Microsoft.Online.SharePoint.PowerShell\Microsoft.Online.SharePoint.Client.Tenant.dll" 
    
#Function to Generate Report on all documents in a SharePoint Online Site Collection
Function Get-SPODocumentInventory($SiteURL)
{
    Try {
        #Setup the context
        $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
        $Ctx.Credentials = $Credentials
    
        #Get the web from given URL and its subsites
        $Web = $Ctx.web
        $Ctx.Load($Web)
        $Ctx.Load($Web.Lists)
        $Ctx.Load($web.Webs)
        $Ctx.executeQuery()
  
        #Arry to Skip System Lists and Libraries
        $SystemLists =@("Converted Forms", "Master Page Gallery", "Customized Reports", "Form Templates", "List Template Gallery", "Theme Gallery",

        Write-host -f Yellow "Processing Site: $SiteURL"
  
        #Filter Document Libraries to Scan
        $Lists = $Web.Lists | Where {$_.BaseType -eq "DocumentLibrary" -and $_.Hidden -eq $false -and $SystemLists -notcontains $_.Title -and $_.ItemCount -gt 0}
        #Loop through each document library
        Foreach ($List in $Lists)
        {
            #Define CAML Query to Get List Items in batches
            $Query = New-Object Microsoft.SharePoint.Client.CamlQuery

You need to make use of Pagingation, as you will be limited to 5000 items! My recommendation for this would be to actually use Power Automate to do this, It's alot easier
