Common friction

lookup formulas break when columns move
missing values are handled inconsistently
teams do not know when to use XLOOKUP
duplicate keys create confusing results

Repeatable process

Test duplicates, blanks, and missing values before copying down.

Before and after example

Better prompt shape

Weak input

A vague request: "Help me with write XLOOKUP formulas." It does not include columns, sample rows, target format, edge cases, or review rules.

Stronger input

A usable request: "Act as an operations analyst. Help me fix lookup formulas and reduce broken spreadsheet references. Input shape: [paste columns and 3 sample rows]. Output: clean table, formula or prompt, assumptions, rows needing review, and next checks."

Review rule
