Frequently Asked Questions

Why convert YAML to JSON?

Many APIs accept only JSON while DevOps tools use YAML (Kubernetes, Docker Compose, GitHub Actions). Converting between formats lets you work with both ecosystems seamlessly.

Does this support Kubernetes manifests and Docker Compose?

Yes. The tool fully supports Kubernetes YAML manifests, Docker Compose files, GitHub Actions workflows, Ansible playbooks, and any valid YAML structure with nesting, lists, and multi-document files.

Is the conversion done on a server?

No. Everything is processed locally in your browser using js-yaml. Your configs with secrets or private data never leave your device, making this safe for sensitive files.

What happens if my YAML has syntax errors?

You'll get a clear error message showing the line and column of the syntax issue. The input field turns red to highlight the problem. This makes it a great YAML validator too.

Can I control YAML output style (block vs flow)?

Yes. Choose between traditional block style (default, most readable), fully inline flow style, or partial block (1-2 levels). This is useful for compact output or human-readable configs.
