Our Salesforce dev team frequently changes field names and without notifying us, so I'm trying to find an easy way to create a report showing all of the columns that contain no data as this is a sign this field was replaced with a new field or is no longer in use and we need to remove it from our ETLs and cards. Is there a way to get a list for each dataset we bring in from Salesforce showing the columns with no values? Is there also a way to pull a list of the cards or ETLs currently using these fields?
