Common friction

anomalies hide inside large sheets
manual review is inconsistent
AI may invent explanations
teams need review queues not guesses

Repeatable process

Define what counts as unusual.
Paste sample rows and metric thresholds.
Ask for flags and confidence levels.
Review high-risk rows before acting.

Reusable prompts

Open prompt pack

Find anomalies in this spreadsheet and separate detected facts from possible explanations.

Flag rows that need manual review based on these thresholds.

Create an anomaly review table with severity, reason, and next check.

Mistakes to avoid

asking AI to explain causes without evidence

Make the prompt more specific, keep the source data visible, and review the output before using it in a live workflow.

not defining thresholds

Make the prompt more specific, keep the source data visible, and review the output before using it in a live workflow.

reviewing only averages

Make the prompt more specific, keep the source data visible, and review the output before using it in a live workflow.

failing to separate flags from decisions

Make the prompt more specific, keep the source data visible, and review the output before using it in a live workflow.
