Frequently asked questions
Is my JSON uploaded?
No. Conversion runs in your browser with the open-source js-yaml library.
Is the YAML output valid for Kubernetes?
Yes. The output is standard YAML with 2-space indentation, accepted by Kubernetes, Docker Compose, GitHub Actions and Ansible.
Are key orders and data types kept?
Yes. Key order is preserved, and numbers, booleans and null stay typed. Strings that would be ambiguous in YAML are quoted automatically.
