Convert JSON and YAML locally in your browser with fast, reliable bidirectional conversion.
Local two-way conversion with auto formatting and syntax validation. Paste/upload to generate instantly; copy or download—ideal for frontend, backend, and DevOps.
All JSON to YAML conversion happens locally in your browser. No data is uploaded to our servers, ensuring complete privacy and security.
API response cleanup, Kubernetes/Ansible/CI configs, and daily conversions/validation for frontend, backend, and DevOps.
JSON to YAML conversion is commonly used for configuration files, CI/CD pipelines, infrastructure settings, and readable examples in documentation.
When converting YAML back to JSON, comments and formatting-only details are not preserved because standard JSON has no comment syntax.
JSON is strict and widely used for APIs. YAML is easier to read in configuration files because it relies on indentation instead of braces and commas.
Use this converter when you need to move between API data, config files, and documentation examples without installing a local CLI tool.
The options panel controls YAML indentation, JSON indentation, line width, and quote style.
YAML comments are not represented in JSON, so they cannot survive a YAML to JSON conversion and back as structured data.
Convert a small sample first when a downstream system has strict YAML rules, then apply the same settings to the full file.
After converting YAML to JSON, validate the JSON before using it in an API request or build step.
Yes. Paste or upload JSON and generate equivalent YAML (YML) in one click, with optional 2/4-space indentation and syntax validation.
Yes. The tool is bidirectional—paste/upload YAML to get JSON while preserving structure and values.
Everything runs **in your browser locally**. No uploads, no login, no ads—safer and more private.
Within standard syntax, data integrity is preserved (objects, arrays, strings, numbers, booleans, null, multi-line strings), with helpful error messages on parse issues.
JSON doesn't support comments. When converting YAML → JSON, comments are removed. JSON → YAML won't invent comments.
We try to keep input order, but **JSON object key order isn't guaranteed**. Don't rely solely on order for logic.
Choose 2 or 4 spaces with auto-formatting. Tabs are not recommended in YAML.
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`).
Yes. Quotes, escapes, and multi-line literal/folded styles (YAML `|` / `>`) are handled to keep output readable and usable.
Use VS Code with relevant extensions, or just use our online converter—paste and go, no setup needed.
`YML` is just a common file extension; it's equivalent to `YAML`.
