What this Lesson covers
Build and verify a workbook map before asking AI to change an unfamiliar Excel file.
Lesson outline
- Know what you are mapping
- Check the source before accepting the map
- Read the map as a set of claims
- Stop where the workbook stops
Learning outcomes
- Set a read-only boundary
- Map workbook structure
- Verify claims in the file
- Stop at missing evidence
An unfamiliar workbook can look orderly while hiding several different kinds of content. One sheet may hold typed records, another may calculate from them, and a third may only repeat allowed labels. If you ask AI to “fix the file” before you know those differences, it can change the wrong cells or treat a summary as if it were the source.
