What is JSON to YAML Conversion?
JSON to YAML conversion transforms JavaScript Object Notation (JSON) data into YAML Ain't Markup Language (YAML) format and vice versa. Both formats are used for data serialization, but they serve different purposes and have distinct advantages.
JSON is widely used in web APIs and data exchange between applications, while YAML is preferred for configuration files, documentation, and human-readable data representation due to its clean, indentation-based structure.
Example Conversion:
JSON:
{
"name": "John Doe",
"age": 30,
"skills": [
"JavaScript",
"Python",
"YAML"
],
"address": {
"city": "New York",
"zipcode": "10001"
}
}
YAML:
name: John Doe
age: 30
skills:
- JavaScript
- Python
- YAML
address:
city: New York
zipcode: '10001'
