Frequently Asked Questions
What is the difference between YAML and JSON?
YAML uses indentation and colons, making it human-readable and common in config files (Docker, Kubernetes, GitHub Actions). JSON uses braces and is standard for APIs. Both represent the same data model and are interchangeable.
Does it handle nested YAML objects and arrays?
Yes. Nested YAML maps become JSON objects and YAML sequences (- item) become JSON arrays. The conversion handles arbitrary nesting depth.
Are YAML booleans converted correctly?
Yes. YAML boolean variants (true, false, yes, no, on, off) are converted to JSON true/false. YAML null values (~ or null) become JSON null.
Can I convert a Kubernetes or Docker Compose YAML file?
Yes. Paste any YAML config — Kubernetes manifests, Docker Compose files, GitHub Actions workflows — and get the equivalent JSON representation.
Is the tool free?
Yes, completely free with no account required.
