What is JSON?
JSON (JavaScript Object Notation) is a lightweight and widely used data format that represents data through key–value pairs, arrays, and objects.
It uses {} for objects and [] for arrays, making it compact and machine-friendly.
Common Uses:
Web APIs and app data exchange
Frontend–backend communication
Storing configuration settings
Since JSON is supported across nearly every programming language, it has become the standard for structured data sharing on the web.
What is YAML?
YAML (YAML Ain’t Markup Language) is a human-readable data format that uses indentation instead of brackets to define hierarchy.
Its clean syntax makes it ideal for writing configuration files and managing infrastructure setups.
Common Uses:
Kubernetes configuration
Docker Compose files
Ansible playbooks
Application and CI/CD settings
YAML is easier to read and edit manually, which is why many developers prefer it for managing system and deployment configurations.
YAML vs JSON : Key Differences
| Feature | JSON | YAML |
|---|---|---|
| Syntax | Uses {}, [], commas, and quotes | Uses indentation and colons |
| Readability | Machine-friendly | Human-friendly |
| Use Case | Web APIs, app data | Configuration files, DevOps tools |
| File Size | Usually smaller | Slightly larger due to spacing |
In short, JSON is great for data exchange between systems, while YAML shines in scenarios where humans frequently edit and read configuration files.
