6. Controlling the format of the output

An AI assistant can answer the same question in dozens of different ways. It might write a long essay, a short sentence, a numbered list, a table, or a poem — it depends on what you ask for.

If you do not say anything about format, the AI picks a style on its own. Sometimes that works fine. But often you have a specific need: you want to paste the output into a report, read it aloud to customers, share it as a social-media post, or print it on a notice board in your shop.

Adding a format instruction at the end of your prompt takes only a few extra words and can save a lot of editing time. It is one of the easiest ways to get a response that is ready to use immediately — no cutting, no rewording, no reformatting.

Here are the most useful format instructions you can give an AI:

1. Bullet points — use when you want a quick, scannable list.

Example: 'Give me the answer as bullet points.'

2. Numbered steps — use when order matters, such as instructions or a how-to guide.

Example: 'Write the steps as a numbered list.'

3. A table — use when you want to compare two or more things side by side.

Example: 'Present the information in a table with two columns: Advantage and Disadvantage.'

4. Short paragraphs — use when the answer needs a bit of explanation but should still be easy to read.

Example: 'Write two short paragraphs, each no more than three sentences.'

5. One sentence / one paragraph — use when you only need a summary.

Example: 'Answer in one sentence only.' or 'Summarise in one short paragraph.'

6. A specific length — set an upper limit in words or sentences.

Example: 'Keep the answer under 80 words.'

7. Plain text only — ask for no bold, no bullet points, and no headings when you will paste the output into a system that does not support formatting.

Example: 'Write in plain text without any bullet points or bold words.'

Seeing the difference between a prompt with no format instruction and one with a clear format instruction helps a lot. Here are two real comparisons:

Situation A — Almaz runs a small coffee shop near Bole, Addis Ababa.

Without format: 'What are the benefits of keeping a daily sales record?'

The AI might write a long essay with five paragraphs — far more than Almaz needs.

With format: 'What are the benefits of keeping a daily sales record? Give me exactly four bullet points. Each bullet should be one short sentence.'

Now the AI gives four short, scannable points that Almaz can pin on her wall or read to her staff in two minutes.

Situation B — Abebe is preparing a two-item price comparison for customers at his electronics shop in Mercato.

Without format: 'Compare a 32-inch TV and a 43-inch TV for a home buyer on a budget.'

The AI might write flowing paragraphs mixing all the points together.

With format: 'Compare a 32-inch TV and a 43-inch TV for a home buyer on a budget. Show the comparison in a table with three rows: Price Range, Screen Size, and Best For. Use two columns: 32-inch and 43-inch.'

Now the AI produces a clean, ready-to-print table.

Beginners sometimes make these format mistakes — they are all easy to fix:

1. Asking for a format that conflicts with the content

Bad: 'Give me a table comparing five products — use one sentence.'

A table and a single sentence are opposites. Pick one.

2. Not specifying the number of items

Vague: 'Give me some bullet points.'

Better: 'Give me exactly five bullet points.'

3. Forgetting the format instruction altogether

The AI defaults to paragraphs. If you wanted a list, you have to ask.

4. Using format words the AI might misunderstand

Vague: 'Make it look nice.'

Better: 'Use bold headings, numbered steps, and keep each step under 15 words.'

5. Asking for a very long output when a short one is enough

If you ask for 'a detailed 1,000-word report' for a simple question, you will spend more time reading than using the answer. Match the length to the need.
