Frequently Asked Questions
How do I convert a JSON object to YAML?
JSON: {"name": "John", "age": 30} → YAML: name: John\nage: 30. JSON arrays: [1, 2, 3] → YAML:\n- 1\n- 2\n- 3. Nested objects use indented sub-keys.
Does JSON-to-YAML conversion add comments?
JSON has no comment syntax, so no comments are present in the source. The converter can add descriptive comments to known fields (when converting Kubernetes or Docker Compose JSON) using the smart annotation feature.
Can I convert a large JSON file to YAML?
The tool handles JSON up to ~5 MB. For larger files, use a command-line tool: python3 -c "import sys,json,yaml; print(yaml.dump(json.load(sys.stdin)))" < input.json > output.yaml
Will YAML-converted output work directly in Kubernetes?
If the JSON represents a valid Kubernetes resource, the converted YAML should be valid kubectl input. However, Kubernetes JSON API responses include additional metadata fields — clean those out before applying the YAML.
What is the indentation convention for YAML?
2 spaces is the most common convention (GitHub Actions, Kubernetes, Docker Compose). 4 spaces is also valid. Tabs are NOT allowed in YAML — they cause parsing errors.
