What's the difference between JSON and XML?

JSON is simpler, more compact, and easier to read. XML supports attributes, comments, and namespaces. JSON dominates for APIs; XML remains common in enterprise systems and configuration.

How do I validate JSON structure?

Use JSON Schema to define expected structure. Tools and libraries validate data against schemas. For quick checks, online JSON validators catch syntax errors.

Can JSON include dates?

JSON has no date type. Common conventions: ISO 8601 strings ("2024-01-15T10:30:00Z"), Unix timestamps (numbers), or custom string formats. Document your format choice.

How do I handle large JSON files?

For large files: streaming parsers (don't load all in memory), pagination for API responses, compression for transfer, and consider binary formats like Protocol Buffers for performance-critical cases.

JSON

JavaScript Object Notation

A lightweight data format for storing and exchanging data. Human-readable and easy to parse, JSON is the standard format for API requests and responses.

In-Depth Explanation

JSON (JavaScript Object Notation) is a text-based data format that's easy for humans to read and write, and easy for machines to parse and generate. It's the dominant format for web APIs.

JSON data types:

String: "hello world"
Number: 42, 3.14
Boolean: true, false
Null: null
Array: ["a", "b", "c"]
Object: {"key": "value"}

JSON structure:

Key-value pairs
Nested objects and arrays
No comments allowed
Strict syntax (double quotes, commas)

JSON advantages:

Human readable
Language independent
Lightweight
Wide support
Easy to parse

JSON limitations:

No date type (use strings)
No comments
Less efficient than binary formats
No schema enforcement (without JSON Schema)

Business Context

JSON is everywhere in modern systems. APIs, configuration files, data storage - understanding JSON is fundamental for integration work.

How Clever Ops Uses This

We work with JSON daily in Australian business integrations - parsing API responses, transforming data between systems, and configuring automation.

Example Use Case

"Receiving customer data from a CRM API as JSON, transforming it, and sending to marketing automation - all data flows in JSON format."
