Common friction

  • bad values enter sheets too early
  • manual cleanup is expensive
  • dropdown rules are inconsistent
  • people do not know what is allowed

Repeatable process

  2. List columns that need controls.
  3. Ask AI for validation logic and helper text.
  4. Test the rules on a copy of the sheet.
