Sometimes you may need to figure out where a specific type of web part has been used. Today, I’ll show you how you can check all pages in your Site Pages library for a specific web part.

I’ve had this code for a while as I was looking for some specific web parts (Content Editor) before. Yesterday, I briefly saw a blog post on announcing the deprecation of the Visio Web Access web part on SharePoint Online (as Visio Online is coming!), though that blog post has disappeared again (I suspect we’ll see it again soon). So I decided to modify it slightly to look for all instances of Visio Web Access web parts and save the results to a CSV file.


The following code checks all pages in the given site’s Site Pages library for instance of the ‘Visio Web Access’ web part. You could easily modify it to loop through all sites in a site collection, or even all sites within your whole tenant.

$cred = Get-Credential
Connect-PnPOnline -Url -Credentials $cred

$visioWebParts = @()

$ctx = Get-PnPContext
$lists = (Get-PnPWeb).Lists
#Note: I'm not accessing the Site Pages library by URL or title, as I had sites in different languages
$sitePages = $lists.EnsureSitePagesLibrary()

$pages = Get-PnPListItem -List $sitePages[0].Id
foreach($page in $pages) {
	$webparts = Get-PnPWebPart -ServerRelativePageUrl $page.File.ServerRelativeUrl
	foreach($webpart in $webparts) {
		$wpxml = Get-PnPWebPartXml -ServerRelativePageUrl $page.File.ServerRelativeUrl -Identity $webpart.Id
		# The Visio Web Access part is referenced in the XML definition of the web part
		# with type Microsoft.Office.Visio.Server.WebControls.VisioWebAccess. Change this for
		# any other types of web parts you want to find 
		if($wpxml -Match '<type name="Microsoft.Office.Visio.Server.WebControls.VisioWebAccess,') {
			$visioWebParts += New-Object PSObject -Property @{
				'PageUrl' = $page.File.ServerRelativeUrl
				'WebPartTitle' = $webpart.WebPart.Title

$visioWebParts | select PageUrl, WebPartTitle | Export-Csv C:\visio.csv
