We have a web application (free for 5 users) that gives you exactly this, and a lot more - it's called Data Controller for SAS
It supports special SAS missing numerics, uploads from Excel, changes to CAS tables / any database, and can even let you change the values in a format catalog. It works on both SAS 9 and Viya. All changes are tracked, and you can set permissions at row level (who can change what). You can also defined data quality rules, and trigger additional jobs when tables are modified.
