Pro Tips
💡YAML uses indentation to define structure — always use spaces, never tabs. Most YAML parsers will reject tab-indented files.
💡YAML comments (
# comment) are lost when converting to JSON — JSON has no comment syntax.💡YAML arrays are denoted with
- (dash) prefix. JSON arrays use [...] brackets. The converter handles this automatically.Frequently Asked Questions
Is all valid JSON also valid YAML?
Yes — YAML is a superset of JSON. All valid JSON can be parsed by a YAML parser. The reverse is not true.
Are YAML comments preserved?
No — YAML comments are not part of the data model and are lost when converting to JSON, which has no comment support.
When should I use YAML vs JSON?
YAML for human-edited configs (Kubernetes, CI/CD). JSON for machine-generated and API data where strict parsing and broad tooling support matter.
Does YAML support comments?
Yes — YAML supports single-line comments with
#. These are ignored by parsers but helpful for documentation in config files.Convert JSON ↔ YAML now
