What YAML features does this support?

The converter handles all standard YAML 1.2 types: strings, numbers, booleans, null, arrays, and nested objects. Multi-line strings, anchors, and aliases work too. Tags and custom types are ignored gracefully.

Why does my YAML with comments fail to convert?

Comments are not part of the YAML data model. They are stripped during parsing — this is expected behavior, not an error. If the conversion fails, the cause is somewhere else in the document.

Can I minify the JSON output?

Yes. Use the Minify toggle to produce compact JSON without whitespace. That output is what you want for API payloads or database columns where size matters.

Is my YAML data sent to any server?

No. Everything runs locally in your browser. Your YAML never leaves your device, and the page works offline after first load.

How are YAML anchors and aliases handled?

Anchors (&name) and aliases (*name) are expanded automatically. The JSON output contains the resolved values, so you can feed it directly into any JSON parser without needing reference support.

YAML to JSON Converter — Convert YAML to JSON Online

Convert YAML to JSON instantly, in your browser. Toova handles every YAML 1.2 feature — multi-line strings, anchors, references, nested mappings, and lists — and gives you back clean JSON in 2-space, 4-space, or minified form.

When you need YAML to JSON

APIs and most programming environments expect JSON, but your configuration files are usually YAML. Whether you are loading a GitHub Actions workflow into a script, debugging a Helm chart, or seeding a database from a fixture file, you often need to flip YAML into JSON quickly. Toova does it in one paste, with no server roundtrip and no signup.

Indent control and validation

Pick 2-space, 4-space, or minified output depending on the destination. The converter validates the YAML on the fly — if the indentation is broken or a value is malformed, you get a clear error pointing to the offending line. Anchors and aliases are resolved automatically, so the JSON output contains the expanded values, not the reference syntax.

Private by default

Every conversion happens locally in your browser. No upload, no logging, no analytics on the content. That makes the tool safe for converting internal configs, infrastructure secrets, or staging fixtures. The DevTools Network tab will stay empty while you work — verify it yourself.
