How can I find a list of Nintex forms and workflows on a site collection or subsite in SPO? I searched around and couldn't find anything
I had this same question a few years ago and there is no feature that I know of to find all your Nintex Forms and Workflows in O365.
If you go to Nintex Customer Central, under Usage,
it shows # of Production Workflows Used, Production Forms Used, Development Workflows Used, and Development Forms Used, so you would think it could also show you where to find them.
I can easily tell that when it tells me I have 35 production forms in use, that number is high. Maybe someone here created a form for testing and then deleted it or deleted the list and it still counts for these numbers, but those numbers are wrong. We maybe have 10 forms in production, at best, so it would be nice to go through and clean up any unused forms.
