Plain definition: JSON (JavaScript Object Notation) is a standard text format for organizing and exchanging data between software systems. It uses a simple structure of labels and values that both humans can read and computers can process reliably.

In plain terms

Imagine a shipping label: it has clearly labeled fields — To, From, Weight, Tracking Number — in a standard layout that any carrier can read and process. JSON is the digital equivalent: a standard layout for data so any app that receives it knows exactly where to find each piece of information. It’s the common language that most apps use when they send data to each other.

Why it matters for operators

You’ll encounter JSON whenever you work with APIs, webhooks, or no-code automation tools. When Zapier receives data from your payment processor and passes it to your CRM, that data travels as JSON. You don’t need to write JSON yourself, but recognizing what it looks like helps you troubleshoot automations and understand what information is moving between your tools when something breaks.

Example

A new order placed on a Shopify store sends a JSON message to a warehouse app. That message includes the customer name, shipping address, and a list of items ordered — all in labeled fields. The warehouse app reads the JSON and automatically creates a pick list. No one keyed in anything.
