How to Use Output Formats in a Prompt

Output formats are one of the simplest yet most powerful tools for improving the clarity, structure, and usefulness of responses from AI. By specifying an output format, you are telling the AI how you want the answer to be presented, rather than leaving it to decide.

Why Output Formats Matter

  • Clarity: Ensures answers are organised in a way that’s easy to read.
  • Consistency: Makes outputs uniform, especially when generating multiple answers for comparison.
  • Efficiency: Saves time reformatting AI responses manually.
  • Actionability: Provides structured data (tables, lists, JSON) that can be copied straight into reports, spreadsheets, or code.

Common Output Formats

1. Bullet Points

Use when: You want quick, scannable insights or lists.

Example Prompt:

“Summarise the key benefits of remote work in bullet points.”

Output:

  • Increased employee flexibility
  • Reduced commuting time and costs
  • Access to wider talent pool
  • Potential cost savings on office space

Benefit: Easy to skim and use in presentations or slide decks.

2. Numbered Lists

Use when: You need a step-by-step process or prioritised actions.

Example Prompt:

“Explain the steps to conduct a successful brainstorming session in a numbered list.”

Output:

  1. Define the objective clearly.
  2. Gather a diverse group of participants.
  3. Use a warm-up exercise to encourage creativity.
  4. Capture all ideas without judgement.
  5. Cluster and evaluate ideas for feasibility.

Benefit: Shows order and priority, ideal for guides and workflows.

3. Tables

Use when: Comparing or categorising information.

Example Prompt:

“Create a table comparing email, chat, and video calls for internal communication.”

Output:

Method Strengths Weaknesses
Email Good for documentation, asynchronous Can be slow, risk of overload
Chat Quick, informal, good for rapid updates Hard to track decisions
Video Call High engagement, good for collaboration Time-consuming, scheduling issues

Benefit: Makes comparisons clearer and easier to present.

4. JSON or Code Blocks

Use when: You need structured data for programming or automation.

Example Prompt:

“Provide three customer profiles in JSON format with fields: name, age, and location.”

Output:

[
  {"name": "Alice", "age": 34, "location": "London"},
  {"name": "Ben", "age": 42, "location": "Manchester"},
  {"name": "Chloe", "age": 29, "location": "Bristol"}
]

Benefit: Ready-to-use data for technical workflows or API calls.

5. Paragraphs or Short Essays

Use when: You want a narrative explanation.

Example Prompt:

“In one paragraph, explain the impact of the printing press on European society.”

Output:

The printing press revolutionised European society by enabling mass production of books, reducing costs, and increasing literacy. This allowed new ideas to spread rapidly, fuelling the Renaissance, Reformation, and Scientific Revolution, and shifting power from elites to a more informed public.

Benefit: Provides a cohesive argument or story, good for reports or educational material.

Tips for Using Output Formats

  • Be explicit: Say “Use a table,” “Write as bullet points,” or “Provide JSON.”
  • Combine formats: Ask for a summary paragraph followed by bullet points.
  • Specify length: e.g. “In 100 words,” or “Limit to 5 bullet points.”
  • Iterate: If the output isn’t quite right, ask the AI to reformat it.

Practical Benefits

  • Speeds up report writing, slide creation, and documentation.
  • Makes information easier to present and share with stakeholders.
  • Reduces rework by getting the output right the first time.
  • Improves collaboration by providing a clear, structured result.
