Does it support YAML anchors and aliases?

Yes. Anchors (&) and aliases (*) are resolved when converting YAML → JSON.

Will it preserve key order in YAML?

Yes. Keys keep insertion order, matching the source object so diffs stay clean.

Can I convert Kubernetes manifests?

Absolutely — multi-document YAML is converted into a JSON array of documents.

Does it support comments?

Comments are stripped on conversion since JSON has no native comment syntax.

Is my YAML stored?

No. We process the input in memory and discard it after returning the response.

What about flow vs block style?

JSON → YAML emits readable block style by default for nested objects and arrays.

Format, validate, minify, and auto-fix JSON in your browser. Fixes trailing commas, unquoted keys, single quotes, comments, and more.

Convert CSV (with headers, custom delimiters) to JSON, or JSON arrays back to CSV. Type-aware parsing, error reporting.

Validate JSON against a JSON Schema, or diff two JSON documents and see exactly what changed. Per-field reports.
