Learn JSON for AI: The One Technical Skill Everyone Needs to Master

Stop being afraid of the curly braces.

If you want to build advanced AI agents, use N8N like a pro, or understand how Boosteam's infrastructure works, you need to learn JSON.

It sounds technical. It looks like code. But here is the secret: It is just a labeled list.

JSON (JavaScript Object Notation) is the standard language that AI agents use to talk to each other. When you ask an agent to "Extract the lead's name," it doesn't reply with a paragraph. It replies with JSON.

If you can read this article, you can master JSON in the next 5 minutes.

Imagine you are an AI agent. You need to send a lead to a CRM.

The Human Way (Unstructured):

To us, this is perfectly clear. But to a computer, it is just a blob of text. It doesn't know if "TechCorp" is a company or a last name. It can't easily filter by "Budget > $10k" because it doesn't know which number is the budget.

The Computer Way (Structured JSON):

{
  "full_name": "Mike Ross",
  "job_title": "VP of Marketing",
  "company": "TechCorp",
  "budget": 50000,
  "demo_requested": true,
  "demo_date": "2025-11-01"
}

See the difference? It's just data in labeled drawers.

You only need to know four symbols. That's it.

1. The Curly Braces { }

This is the Container. It says "Here is a single object." Everything inside the curly braces belongs to that specific item (like a specific Lead, or a specific Ad).

2. The Quotes " "

This is for Text. If you are writing a word or a sentence, wrap it in double quotes.

• Correct: "campaign_name": "Q4_Retargeting"
• Incorrect: "campaign_name": Q4_Retargeting

3. The Colon :

This is the Connector. It connects the Label (Key) to the Data (Value).

• "Label": "Data"

4. The Square Brackets [ ]

This is a List. Use this when you have multiple items of the same type.

• "tags": ["b2b", "high_intent", "usa"]

Let's look at how a Facebook Ad Set looks to an AI agent.

{
  "campaign_name": "US_SaaS_Prospecting",
  "daily_budget": 200,
  "status": "ACTIVE",
  "targeting": {
    "location": "United States",
    "age_min": 25,
    "age_max": 65,
    "interests": ["Marketing Strategy", "SaaS"]
  },
  "creative_ids": [101, 102, 105]
}

Can you read it? Of course you can.

• "targeting" is a nested object (it has its own curly braces).
• "interests" is a list (square brackets).
• "daily_budget" is a number (no quotes needed for numbers).

JSON is strict. If you miss a comma, it breaks. Here are the two most common mistakes:

1. The Trailing Comma: You cannot have a comma after the last item in a list or object.
   • Bad: {"name": "Mike",}
   • Good: {"name": "Mike"}
2. Smart Quotes: Always use straight quotes ("), not the curly "smart quotes" that Word/Google Docs create.

Congratulations. You now understand the data format that powers 90% of the modern web and 100% of AI agents.

Next time you see a block of code in Zapier or Boosteam, don't panic. Just look for the { curly braces } and read the labels.
