YAML to JSON Converter

Paste a YAML file below - a Docker Compose file, Kubernetes manifest, or CI pipeline config - to get back valid, properly nested JSON.

This is often the fastest way to sanity-check a YAML file’s structure: if it converts cleanly, the indentation is valid.

Frequently Asked Questions

Does it support multi-document YAML (separated by ---)?

The converter parses the first YAML document in the input. For multi-document files, convert each document separately.

What about YAML anchors and aliases (&, *)?

Standard YAML anchors/aliases are resolved during parsing, so the resulting JSON contains the fully expanded values.
