Output will appear hereYAML to JSON conversion
JSON Mint uses a full YAML 1.2 parser, so anchors, aliases, flow and block styles, multi-line strings, and typed scalars all work. The output is standard JSON with two-space indentation. Everything runs in your browser — YAML never touches a server, so you can safely convert files containing secrets or internal configuration.
Common use cases: converting a GitHub Actions workflow into JSON for programmatic analysis, turning a Kubernetes manifest into an API body, or exporting a config file for a tool that only understands JSON.
Frequently Asked Questions
Are YAML anchors and aliases supported?+
Yes. Anchors are expanded when converting to JSON, since JSON has no reference mechanism.
What if my YAML has multiple documents?+
Only the first YAML document is converted. Paste documents individually or merge them into a list first.
Does it validate YAML syntax?+
Yes. If the YAML is malformed, the tool shows the parser error so you can fix it.
