A short script to find all content types added to all of your lists in a given site collection and its subsites.


Very useful if you receive an error message:


when trying to remove a content type.




How to use?

1. Download and install SharePoint Online SDK.

2. Download the .ps1 file.

3. Open the file (you can do it also in NotePad)

4. Insert your data in these lines:



 # Paths to SDK. Please verify location on your computer. 
Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll"  
Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"  
# Insert the credentials and the name of the admin site 
$AdminPassword=Read-Host -Prompt "Password" -AsSecureString 
a) Find on your computer where SharePoint.Clitent.dll and SharePoint.Client.Runtime.dll libraries are located and insert the correct paths
b)  Instead of "admin@tenant.onmicrosoft.com" enter you username
c) Instead of "https://tenant.sharepoint.com/sites/teamsitewithlibraries" enter the name of the site collection where you want to find the content types



5. Run the script in Powershell (any module). 

6. The result should show the table of names and associated lists and websites where those lists are located




You can also export it to CSV:
