What YAML features does this converter support?

It supports key-value pairs, nested objects, arrays, block scalars (| and >), inline arrays/objects, comments, booleans, null, numbers, hex/octal literals, and the --- document separator.

Does it handle Kubernetes and Docker YAML files?

Yes. Kubernetes manifests and Docker Compose files are standard YAML and convert cleanly. Multi-document YAML (--- separator) is supported and processed as a single document.

Is my YAML data sent to any server?

No. All conversion runs entirely in your browser using JavaScript. Your data never leaves your device — no server, no logs, no storage.

Can I convert JSON back to YAML?

Yes. Click the Swap button or select the JSON → YAML mode to switch directions. Paste any valid JSON and get well-formatted YAML output instantly.

What happens if my YAML has a syntax error?

A red error banner appears above the output with the exact error message. Fix the YAML and the banner disappears automatically when the input becomes valid.

Can I use this for GitHub Actions and CI/CD YAML files?

Yes. GitHub Actions, GitLab CI, CircleCI, and other pipeline YAML files are all supported. The converter handles complex nested structures and arrays.

Can I minify the JSON output?

Yes. Toggle off the Pretty Print switch and the output switches to compact single-line JSON — useful for API payloads or reducing file size.

What is the difference between YAML and JSON?

YAML is a human-readable format that uses indentation for structure (common in config files). JSON uses curly braces and brackets (common in APIs). Both represent the same data types.

Can I download the converted file?

Yes. Click the Download button to save the converted output as a .json file (in YAML→JSON mode) or a .yaml file (in JSON→YAML mode).

Is there a file size limit?

The tool handles YAML and JSON files up to approximately 1MB comfortably in the browser. For very large files consider the CLI tool yq or jq.
