I need to delete duplicate SharePoint records in a list made up of users' equipment (fields like "Service Tag", "Barcode", and "Approval ID" etc. I have been trying in vain to apply lessons I've seen here and elsewhere on how to effectively (1) identify the duplicates and (2) delete them, or at least update the records in some way I can then manually delete them. I have seen a lot of posts with ideas that should help, but I either delete all the records or none of them... Right now, the list is around 500-800 records, but it will likely grow exponentially in the next few weeks as it captures our 7,000 users' information.
