About this tool

How the YAML to JSON works

Convert YAML configuration files into formatted JSON. 100% private in-browser parsing for Kubernetes, Docker Compose, and CI/CD pipelines.

DevOps & Cloud Ready

Perfect for Kubernetes manifests, GitHub Actions workflows, Docker Compose, and Ansible files.

Nested Structure Parsing

Accurately maps YAML indentations, lists (-), and key-value pairs into nested JSON objects.

Formatted Output

Generates clean, 2-space indented JSON ready for API consumption.

Offline Execution

Processes configurations entirely in browser memory without sending infrastructure configs over the wire.

FAQ

Common questions

Why convert YAML to JSON?

Many APIs, data stores, and command-line tools (like jq) only accept JSON. Converting YAML to JSON enables automated querying and verification.

Are YAML lists and arrays supported?

Yes, YAML dash items (- item) are seamlessly translated into JSON arrays.

Is it safe to paste private infrastructure configs here?

Yes! Everything runs client-side in your local browser with zero server transmission.

Can I format the resulting JSON with different indentation?

Yes, you can choose between 2 spaces, 4 spaces, or compact tabs.
