Simply paste the Url from the “Modify View” page in SharePoint and it will generate the List ID and View ID for you.

 

List ID:      
View ID:     

 

I got tired of doing this in notepad, so I built this as an easy way to get a SharePoint List ID or View ID from a Url.

For the list ID, go to List Settings, and copy the Url, and paste the url in the box.
For the list ID and the View ID, go to a list view, and click “Modify View,” and copy the url in the box.

Paste the url in the box and press ‘Submit’
