Day 100: Find the story hiding in a small spreadsheet.
A small table can contain a useful pattern, but one duplicate or mismatched date can create a convincing false lead. Attach a non-sensitive CSV or spreadsheet and paste this prompt: "Inspect this spreadsheet before drawing conclusions; list every column and its apparent type; count missing values by column; identify duplicate rows and the columns used to define a duplicate; flag inconsistent dates, numbers, currencies, categories, and text formats; then report patterns and anomalies with exact row numbers and calculations; use two sections titled Observations and Interpretations; put only verifiable spreadsheet facts in Observations, show the calculation behind each claim, and put possible explanations in Interpretations with uncertainty clearly labeled; do not invent missing context, and ask me questions when a field is ambiguous."
Do not begin with a chart; begin by checking the AI's column inventory, missing-value counts, duplicate definition, and format warnings against the sheet. Next, trace every reported pattern or anomaly to the cited rows and redo one calculation with a spreadsheet formula or calculator. You will end with an audit trail that separates what the cells show from what those facts might mean.
Tomorrow, we will question a document before filing it so dates, references, and actions do not disappear.
