I was looking for this tool and found it when someone linked to it. Running now on my old Steem posts. Thanks.
Update: I am running a prune and it has stopped after about a quarter of the posts. I do have rather a lot. Should I leave the page open or can I run it again. Does it do any harm to re-run? Does it skip those already done?
Okay, I stopped and re-started it. Looks like it does the right things. Thanks again.
