How it works
YAML ↔ JSON Converter — Convert between YAML and JSON in either direction. All processing happens in your browser — no upload, no signup, no email required. Free forever.
Frequently asked questions
Are anchors and aliases preserved?
When converting YAML → JSON, anchors and aliases are resolved to their referenced values (JSON has no anchor concept). The reverse direction emits plain YAML without anchors.
How are dates and special types handled?
We use the YAML 1.1 default schema. Dates parsed in YAML come out as ISO-8601 strings in JSON. Booleans, numbers and nulls are preserved as native JSON types.
Is my data uploaded?
No. Both directions of conversion run in your browser via js-yaml — nothing is sent anywhere.
