I am trying to delete a number of old tags PI tags and duplicates through PI builder in excel. We have an excel list of the point names we want to delete but I don't know how to do it efficiently. I was told that there used to be an import command in which I could just copy and paste all the point names I need to delete into PI builder. Then the import command would be used to pull the information from PI into excel then I could just delete the tags. If I can clarify anything please let me know, thanks for any help.
