Schema
The list of fields the data must have, with the type of value each one holds.
Say it to an AI
Extract every review in the attached CSV into a JSON array: one object per review with keys id, rating (integer 1–5), complaint (max 8 words, or null), mentions_price (boolean). Output only the JSON, no prose.
How an expert would ask for the stronger version of “Review data for a dashboard”.
See it
Try it as a puzzle →A developer asks an AI to pull data out of 40 app store reviews so a script can load it into the team's dashboard.
Why: B defines 'rating (integer 1–5)', 'complaint (max 8 words, or null)' and 'mentions_price (boolean)', so review 2's missing complaint comes back as null, not as a sentence.
