How it works

The converter walks your YAML line by line, tracking indentation to rebuild the nested structure, casts scalars to numbers, booleans and nulls, then serialises the result as indented JSON.

Frequently asked questions

Is my YAML uploaded anywhere?

No. Parsing happens entirely in your browser, so configuration files and secrets never leave your device.

Which YAML features are supported?

Nested maps, sequences, comments, quoted strings and scalar types. Anchors, aliases and multi-document files are not.

Comments

Comments aren't enabled yet. When you're ready, this is where a service like Giscus, Disqus, or a custom form would go — the slot is already reserved on every tool page.
