JSON → YAML

Does this JSON to YAML tool upload my data to any server?

No. All JSON parsing and YAML generation happen completely in your browser using js-yaml. Nothing is uploaded or stored externally.

Why am I seeing a 'Failed to parse JSON' error?

The tool uses JSON.parse, which requires strictly valid JSON. Common issues include missing quotes, trailing commas, or malformed structures. Fix the syntax and try again.

What does the indentation setting do?

You can choose between 2-space and 4-space indentation. This controls how nested YAML structures are visually formatted.

What happens when I enable 'Sort object keys alphabetically'?

When enabled, all object keys in your JSON are sorted alphabetically before conversion. This helps produce cleaner and more predictable YAML output.

Can I upload a JSON file directly?

Yes. You can upload any .json file and its contents will be loaded instantly into the JSON input panel for conversion.

Why is my YAML empty after converting?

If your JSON input is invalid or empty, YAML generation fails and the output remains blank. Correct the input and convert again.

Does the tool preserve arrays and nested objects?

Yes. Arrays become YAML lists and nested objects are represented with proper indentation according to the selected settings.

Why does Download YAML sometimes not work?

The Download button is enabled only when valid YAML exists. If conversion fails or the input is empty, downloading is disabled.
