Quick tips for YAML to JSON
# YAML input
apiVersion: v1
kind: ConfigMap
metadata:
name: app-config
data:
database_url: postgres://localhost/db
debug: true
ports:
- 8080
- 8081
// JSON output
{
"apiVersion": "v1",
"kind": "ConfigMap",
"metadata": {
"name": "app-config"
},
"data": {
"database_url": "postgres://localhost/db",
"debug": true,
"ports": [8080, 8081]
}
}Convert between formats and work with configuration files using these complementary tools.
Convert XML documents to JSON format, similar to YAML conversion for structured data.
Format and validate the JSON output from YAML conversion before using it in production.
Generate JSON Schema definitions from the JSON you converted from YAML configs.
Create TypeScript interfaces from YAML-converted JSON for type-safe configuration handling.
The converter supports standard YAML features including scalars, sequences (arrays), mappings (objects), multi-line strings, and basic YAML syntax. Complex YAML features like anchors and references may have limited support.
YAML comments are typically stripped during conversion to JSON since JSON doesn't support comments. The conversion focuses on the data structure rather than preserving comments.
Yes, the converter can handle deeply nested YAML structures with multiple levels of objects and arrays. The resulting JSON will maintain the same hierarchical structure.
YAML data types are converted to their JSON equivalents: strings remain strings, numbers become JSON numbers, booleans stay as booleans, and null values are preserved. YAML's additional data types are converted to their closest JSON representation.
