My org has been around for quite a while and some admins were more meticulous than others about cleaning up old single- and multi-select picklist values.
Well, I'm one of the more-meticulous sort and I'd like my users to have clean data.
Is there a pre-existing way to go through my org, picklist field by picklist field, and find out which values are in records and no longer in the metadata, and then figure out how to fix them? I can easily write the Batchable class, but it seems like someone else already has.
