What is YAML
YAML (YAML Ain't Markup Language) is a human-friendly data serialization language, commonly used for configuration files and data exchange.
What is JSON
JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate.
YAML vs JSON
YAML is more readable and supports comments, while JSON is more widely supported and faster to parse. Each has its own use cases.

Convert between different config file formats
API Development
Transform API request/response data formats
Data Transfer
Convert data between different systems
Documentation
Format examples in technical documentation
DevOps

YAML uses indentation (spaces) for structure - tabs are not allowed
JSON requires double quotes for string keys and values
YAML supports comments with #, but JSON does not
Check syntax errors carefully - the error message will show the exact location
Use appropriate indentation size for better readability
