The Secret Power of JSON Prompts

A custom GPT to turn messy prompts into JSON prompts (included)

Why structure beats “vibes” when talking to AI

Most creators are still talking to AI like it’s a friend at a coffee shop.

“Hey, can you write me something inspiring about productivity?”

And then they get… a generic paragraph. Bland. Forgettable.

Just remember this…
LLMs aren’t humans. They don’t understand language like we do. They predict patterns. And the clearer the pattern, the sharper the output.

That’s why I stopped writing prompts like sentences—
and started writing them like code.

The shift?
I began writing in JSON format.

It feels like filling out a form instead of begging a genie.
And the results? Shockingly more accurate, more structured, and more useful.

Today, I’ll show you how to use JSON prompts to get consistent, high-quality outputs…whether you’re writing tweets, Substack notes, newsletters, or even building digital products.

What is JSON Prompting?

Most people think “prompting” means typing a sentence into ChatGPT and hoping it understands.

But there’s a smarter way: JSON prompting.

Instead of writing in free-flowing English, you put your request into a structured format… like a form for the AI to fill out.

Here’s a simple example for our world as creators 👇

Regular prompt:

“Write me 3 newsletter subject line ideas about building an audience.”

JSON-style prompt:

{
  "task": "generate subject lines",
  "platform": "email newsletter",
  "topic": "audience growth for solo creators",
  "tone": "curious and punchy",
  "output_format": "list of 3"
}

See the difference?

The first is vague.
The second is clear, modular, machine-readable.

When you give AI structured instructions, you’re not leaving it to “guess” what you mean. You’re telling it exactly what you want.

Think of it like this:

A regular prompt is like saying “draw me something nice.”
A JSON prompt is like handing the AI a blueprint with exact requirements.

Why JSON Prompting Works

Here’s the secret:
AI models don’t “think.” They don’t understand nuance the way we do.

They recognize patterns.

And JSON is the ultimate pattern.
It’s structured. It’s precise. It removes all ambiguity.

That’s why JSON prompts produce sharper outputs:

No guessing. The AI doesn’t have to interpret your intent—it just follows the keys and values.
Code familiarity. LLMs are trained on code, APIs, and structured data. JSON looks like their native environment, so they respond with higher accuracy.
Clear modularity. You can change just one part of a JSON prompt (like tone, platform, or audience) without rewriting the whole thing.

Think of it like briefing a designer:

If you say “make me a cool logo,” you’ll get something random.
If you say “make me a clean logo in blue and white, minimalist style” you’ll get exactly what you want.

That’s what JSON prompting does…it removes vagueness and turns your request into a blueprint AI can’t ignore.

Side-by-Side: Freeform vs JSON

Let’s make this real.

Imagine you’re creating content to grow your audience.

Freeform prompt:

“I want to create a LinkedIn post about JSON prompting, can you create a post about this?”

Here is the output I got from ChatGPT:

Now, the JSON version:

{
  "task": "generate_social_post_ideas",
  "platform": "linkedin",
  "topic": "JSON prompting for sharper AI outputs",
  "audience": "solo creators and independent consultants",
  "quantity": 1,
  "idea_style": "problem-solution with proof",
  "output_format": "list with hook + angle"
}

Here is the output I got:

Which one do you think is good? (Share your thoughts in the comments.)

Advanced JSON Prompting (Nested Prompts)

Once you get comfortable with basic JSON prompts, you can take it a step further: Nesting.

This means breaking your request into smaller structured parts…like giving AI a playbook instead of just the title of the game.

Here’s what that looks like for a LinkedIn post:

{
  "task": "write a LinkedIn Post",
  "topic": "using AI to scale as a solo creator",
  "audience": "newsletter writers and consultants",
  "structure": {
    "headline": "short, curiosity-driven, under 10 words",
    "introduction": "story-driven hook, 2-3 sentences",
    "body": "3 sections with actionable tips + examples",
    "conclusion": "1 key takeaway + light CTA"
  },
  "tone": "clear, confident, practical"
}

What happens here?

The AI doesn’t just “write a LinkedIn post.”
It follows your structure, piece by piece.
You end up with a modular draft that feels like something you can publish, not something you need to rewrite from scratch.

Think of nesting like building blocks:

Each key is a part of your final output.
Change one block, and the rest still holds together.

This is how you go from “prompt spaghetti” → to clean, reusable frameworks.

5 High-Leverage Use Cases with JSON Prompts

The real magic of JSON prompting is how flexible it is.
You can take the same skeleton and apply it to almost any task you do as a creator.

Here are 5 high-leverage ways to use it 👇

Note: these prompts are very basic, and this is for demonstration purposes. For example, for the “audience,” I wouldn’t just say “solo creators.” So when you are using these prompts, I highly recommend giving as many details as possible.

1. Newsletter Drafting

{
  "task": "write newsletter draft",
  "audience": "solo creators",
  "topic": "growing an audience without burnout",
  "structure": {
    "hook": "short story or bold statement",
    "lesson": "3 insights with examples",
    "cta": "encourage readers to reply or share"
  },
  "tone": "friendly and practical"
}

👉 Use this to go from idea → publish-ready draft in minutes.

2. Social Media Posts (X / LinkedIn)

{
  "task": "generate social posts",
  "platform": "LinkedIn",
  "topic": "content systems for consultants",
  "output_format": "5 posts with hooks + angles",
  "tone": "authoritative but relatable"
}

👉 Stop staring at a blank page. Start with structured post ideas.

3. Landing Page Copy

{
  "task": "write landing page copy",
  "product": "AI-Powered Content System",
  "audience": "newsletter writers and solopreneurs",
  "structure": {
    "headline": "big promise in under 10 words",
    "subheadline": "clarify benefit in one sentence",
    "sections": ["problem", "solution", "social proof", "CTA"]
  },
  "tone": "clear, benefit-driven"
}

👉 Your sales pages won’t sound generic anymore.

4. Coaching & Consulting Deliverables

{
  "task": "create client deliverable",
  "input": "notes from a 1:1 strategy call",
  "deliverables": ["audience profile", "content roadmap", "3 monetization ideas"],
  "output_format": "markdown with headers",
  "tone": "strategic and simple"
}

👉 For turning call notes into polished docs your clients will love.

5. Research & Content Summaries

{
  "task": "summarize research",
  "input": "paste article or transcript",
  "audience": "solopreneurs",
  "length": "200 words",
  "tone": "curious and insightful",
  "output_format": "summary + 3 key takeaways"
}

👉 Saving time and pulling insights fast.

When Not to Use JSON

Now, here’s the nuance.

JSON prompting isn’t a silver bullet.
There are moments when structure actually gets in the way.

Think about it like this:

JSON is great for precision.
But sometimes you want chaos.

Here are the cases where freeform works better:

Brainstorming wild ideas.
When you don’t want limits—like naming a new product or exploring future trends.
Creative writing.
Stories, analogies, or personal essays often flow better without constraints.
Exploration and play.
Dream journaling, mind-mapping, or idea generation benefit from open-endedness.
Sparking surprise.
If your goal is novelty over clarity, freeform prompts will often give you results you couldn’t have predicted.

The rule of thumb is simple:

Use JSON when you want accuracy.
Use freeform when you want discovery.

Both are powerful. The win is knowing when to switch gears.

Most people “ask” AI for things.
That’s why they get vague, surface-level answers.

But when you switch to JSON prompting, you stop asking…
and start specifying.

You’re no longer throwing vibes at a black box.
You’re giving the model a blueprint…task, audience, tone, structure, format.

That shift changes everything:

Fewer rewrites
Faster drafts
Outputs that actually feel publish-ready

And here’s the bigger win:
Writing prompts this way doesn’t just help the AI…it helps you.

You’re forced to define your goals, clarify your audience, and decide the structure before you hit enter.

That’s what separates “random outputs” from results that move your business forward.

So next time you’re about to type a prompt, ask yourself:
👉 Do I need structure or chaos?

If it’s structure, JSON is your secret weapon.
And to make it effortless, I built you a custom GPT:
