YAML to JSON Converter
Convert YAML into valid JSON instantly in your browser. This is useful for API payloads, config migrations, and debugging CI/CD files. If you need to go the other direction, use our JSON to YAML tool.
How to Use
- Paste YAML into the left box.
- Click Convert.
- Copy the formatted JSON output.
When This Helps
Developers often receive YAML from Kubernetes manifests, GitHub Actions, and IaC templates but need JSON for APIs or validation tooling. Pair this with our JSON formatter to inspect large results quickly.
Common YAML to JSON Workflows
- CI pipeline debugging: Convert workflow snippets into JSON so you can compare structure in API docs and logs.
- Kubernetes checks: Validate nested arrays and object fields before applying deployment changes.
- Config migration: Move legacy YAML settings into JSON-based app configuration formats.
Formatting Notes
This converter outputs pretty-printed JSON with two-space indentation. That makes nested keys easier to read and safer to copy into tools that validate request bodies.
FAQ
Does this upload my YAML?
No. Conversion happens entirely in your browser.
Does it support advanced YAML?
It supports common mappings and arrays used in day-to-day configs. Highly custom YAML tags are not handled.
Why did my output become null?
If your YAML is empty or only comments, the parser may return an empty value. Add actual key-value pairs to generate JSON output.
Can I convert JSON back to YAML here?
This page is one-way. To reverse the process, use JSON to YAML.
