This looks like just what I needed when I built my "admin ui" last year.
Instead of building an admin ui with Django or similar, I encourage you to just stick with a web-based spreadsheet for your internal users (if you have a small team, technical teammates, startup, etc).
In that case you may not even need to build a web based one. There's lots of nice DB GUIs which will connect over an SSH tunnel. If you're after a record editor, they're often enough.
