Frequently Asked Questions
Why convert JSON to YAML?
YAML is more human-readable and supports comments, making it perfect for configuration files. It's the standard format for Docker Compose, Kubernetes manifests, GitHub Actions, and Ansible playbooks. If you're working with any of these tools, YAML is usually easier to maintain than JSON.
What's the difference between JSON and YAML?
YAML uses indentation instead of brackets, supports comments with #, and doesn't require quotes around most strings. It's less verbose and easier to read, but more sensitive to spacing. JSON is stricter and better for data exchange between systems, while YAML is better for human-edited config files.
Does YAML support everything JSON does?
Yes, YAML is a superset of JSON—any valid JSON is also valid YAML. You can convert JSON to YAML without losing data. However, YAML has extra features like anchors, aliases, and multi-line strings that don't exist in JSON.
Can I customize the YAML output?
Yep! Click Settings to control indentation (2 or 4 spaces), key sorting (alphabetical or original order), and whether to quote strings. This lets you match your project's formatting standards.
Is my data safe?
Everything runs in your browser. Your JSON never gets uploaded anywhere—it's converted locally using JavaScript. No servers, no storage, completely private.
