external XSLT is expiring in classic sites

Question

Hi,

As per MS, support for external XSLT files references in the DataFormsWebPart and its subclasses will no longer be available after March 14, 2021.

Is there a way we can conduct an audit of DataFormWebParts for all classic SharePoint pages?

Answer 1

Hi anonymous user,

Per my research, I could not find a way to directly conduct an audit of DataFormWebParts for all classic SharePoint pages.

As a workaround, please use following PnP Powershell to get web parts from all pages on the site and create a CSV report:

#Parameters  
$SiteURL = "https://crescentintranet.sharepoint.com/sites/vendors"  
$CSVPath = "C:\Temp\Webparts.csv"  
$WebPartsData = @()  
   
#Connect to SharePoint Online site  
Connect-PnPOnline -Url $SiteURL -UseWebLogin  
   
#Get all pages from "Site Pages" library  
$SitePages = Get-PnPListItem -List "Site Pages"   
   
#Iterate through each page  
ForEach($Page in $SitePages)  
{  
    #Get All Web parts from the page  
    $Webparts = Get-PnPWebPart -ServerRelativePageUrl $Page.FieldValues.FileRef  
   
    #Iterate through webparts and collect details  
    ForEach($Webpart in $Webparts)  
    {    
        #Get Web part properties  
        $WebPartsData += New-Object PSObject -Property @{  
                "PageUrl" = $Page.FieldValues.FileRef  
                "WebPart ID" = $Webpart.Id  
                "WebPart Title" = $Webpart.WebPart.Title  
                "Is Closed" = $Webpart.WebPart.IsClosed                  
                "Hidden" = $Webpart.WebPart.Hidden  
                "Zone Index" = $Webpart.WebPart.ZoneIndex  
                "Allow Hide" = $Webpart.WebPart.Properties.FieldValues.AllowHide  
            }         
    }  
}  
#Export Web part data to CSV  
$WebPartsData  
$WebPartsData | Export-Csv -Path $CSVPath -NoTypeInformation  

Then try to filter all DataFormsWebParts with web part title.
