Frequently Asked Questions
Can I convert JSON to YAML?
Yes. Paste or upload JSON and generate equivalent YAML (YML) in one click, with optional 2/4-space indentation and syntax validation.
Is reverse conversion supported (YAML → JSON)?
Yes. The tool is bidirectional—paste/upload YAML to get JSON while preserving structure and values.
Is conversion done locally? Is any data uploaded?
Everything runs **in your browser locally**. No uploads, no login, no ads—safer and more private.
How accurate is the result? Will data be lost?
Within standard syntax, data integrity is preserved (objects, arrays, strings, numbers, booleans, null, multi-line strings), with helpful error messages on parse issues.
Are comments preserved?
JSON doesn't support comments. When converting YAML → JSON, comments are removed. JSON → YAML won't invent comments.
Will key order change?
We try to keep input order, but **JSON object key order isn't guaranteed**. Don't rely solely on order for logic.
How do I set indentation and formatting?
Choose 2 or 4 spaces with auto-formatting. Tabs are not recommended in YAML.
Do you support very large files?
It depends on browser memory and device performance. A few MB to tens of MB usually works; larger files are better split or handled via CLI tools (e.g., `yq`/`jq`).
Are special characters and escaping handled automatically?
Yes. Quotes, escapes, and multi-line literal/folded styles (YAML `|` / `>`) are handled to keep output readable and usable.
How do I convert JSON → YAML in an editor?
Use VS Code with relevant extensions, or just use our online converter—paste and go, no setup needed.
What's the difference between YAML and YML?
`YML` is just a common file extension; it's equivalent to `YAML`.
What are typical use cases?
API response cleanup, Kubernetes/Ansible/CI configs, and daily conversions/validation for frontend, backend, and DevOps.
