Removeing placeholder sheets

I have a list of sheets that I want to remove from placeholder, I tried to use Sheets.IsPlaceholder from archilab but with no luck, any ideas

Please find ** Purge Existing Placeholder Sheets** post in https://andrewkingme.com/work/Excel-Sheet-Index-to-Revit/
Hope this useful.
Best Regards,

You can do that with a few nodes from Archi-lab.net package.

Cheers!

ps. I am deleting all placeholder sheets like this, but you can expand the filter to just get some that match some parameter like name. I will leave that to you to sort out.

Thanks, Venkat and Konrad; problem resolved and I was able to delete sheet placeholder with both scripts.
