Excel reporting formula test cases
Copy-ready test cases for reviewing Excel reporting formulas before using them in dashboards or recurring reports.
Use this when a formula feeds a report and silent errors would be more expensive than a slower review.

Copy-ready prompt patterns
Core tests
Check formula behavior before filling down.
- One normal row.
- One blank row.
- One duplicate-key row.
Reporting tests

Before and after
This formula seems to work.
Create test cases for normal rows, blanks, duplicates, missing lookups, date boundaries, and source-total checks before using the formula in a report.
What makes this useful
- Shows the input shape, not just the task name.
- Separates drafting from review.
- Works as a source page for internal linking and external reference.
- Can be reused in recurring workflows.
Before and after examples
Lookup formula
Before
XLOOKUP returns blank for missing IDs and the dashboard hides the issue.
After
Missing IDs return Review Needed and test rows confirm text/number ID behavior.
Prevents silent reporting gaps.
Date filter
Before
A monthly report formula includes rows from the wrong date boundary.
After
Test rows cover first day, last day, blank date, and timezone-shifted exports.
Useful for recurring reports and client dashboards.
Duplicate key
Before
SUMIF uses a duplicated account key and totals look too high.
After
Duplicate-key test rows show whether the formula should sum, pick latest, or flag review.
For reporting formulas, duplicate behavior must be explicit.
Common failure cases
FAQ
Use at least one normal row, one blank row, one missing lookup, one duplicate key, and one date-boundary row.
AI can generate edge-case rows, explain expected outputs, and compare formula behavior against manual calculations.
Dashboard formulas can hide errors behind totals and charts, so small row-level mistakes can become trusted but wrong reports.
