Specify the Output Format

Principle: Tell the AI exactly how you want the answer shaped — a list, a table, JSON, a specific length — and it will deliver something you can use right away.

Ask for the shape you need

Format requested

List 5 healthy breakfast ideas. Format as a table with columns: Meal, Main ingredients, Prep time.

| Meal | Main ingredients | Prep time |

...

Useful format instructions

  • "Answer in exactly 3 bullet points"
  • "Return the result as a numbered list"
  • "Give the output as a table with these columns: ..."
  • "Respond only with valid JSON, no explanation"
  • "Keep it under 100 words"

Why it helps

A defined format removes guesswork and makes the output easy to paste into a document, spreadsheet, or program. It is one of the fastest ways to upgrade your results.

💡 Tip: for anything you will reuse (data, code, lists), always state the format. It saves cleanup later.
