Enforcing output format
Request a fixed format such as a table, checklist, or JSON.
After this lesson
You get output that you can copy directly or process further.
In view · Along the same yardstick
A result with fixed sections
Request, for example, a table, checklist or small JSON object.
Describe mandatory fields and what should happen with missing information.
Check whether the format is usable and the values are correct.
Part 1 of 3 · Choose the format
Your preference for less movement is on. Choose each part yourself.
Be explicit
Say exactly which format you want: table, numbered list, checklist.
Provide the structure
For example: “Provide the answer as a table with columns A, B, and C.”
Check
Check if the format is correct before using it further.
New practice example
From explanation to a usable result.
A fixed format helps with processing. It does not guarantee that the content of the fields is correct.
Fictional practice situationFictitious note: “Noor is making the poster.” There is no deadline. You want a table with task, owner and deadline.
View a possible solution
This is how it can be done
Task: making poster. Owner: Noor. Deadline: TBD. With JSON, you can agree in advance that a missing deadline becomes null instead of a made-up date.
Why this works
A neatly formatted table or valid JSON can still contain incorrect information. Substantive validation remains necessary.
Make it slightly more difficult
Add a second action without an owner and describe how to unambiguously record both a missing owner and deadline.
Extra practice, at your own pace. You do not need to submit anything. This does not count towards an automatic assessment.

Build a prompt and compare the versions
Switch off context and boundaries. Which instructions disappear from your task?
Vague start
Write a customer email.
Your constructed prompt
Write a friendly customer email about changed opening hours.
Not yet explicitly provided: context and source facts, format and target audience, boundaries and control.
This trial works locally with fictitious data and does not count towards your lesson completion. It starts anew with a new lesson or reload.
A prompt to get you started
Provide the answer as a numbered checklist of maximum 5 points. Each point must start with a verb. Subject: [subject].
Apply it
A follow-up system expects JSON with title and status. The model returns JSON plus an explanatory paragraph.
Which approach best fits this situation?
- Validate the format and have invalid output corrected or rejected.
- Send the invalid output to the follow-up system anyway.
- Assume that only the instruction answer in JSON is sufficient.
With JavaScript, you can check your approach and receive immediate feedback.
Test your insight
Why is a fixed output format useful?
- It looks better.
- You can use the result immediately or process it further.
- AI will no longer make mistakes.
Extra practice
Write a prompt that enforces a fixed format. Choose table, checklist, or numbered list.
“Provide the result as a table with columns: risk, impact, measure.”
