About YAML to JSON

The YAML to JSON Converter parses YAML configuration and returns equivalent JSON that your code, tools, and APIs can consume directly. It's ideal for pulling values out of a Docker Compose file, Kubernetes manifest, or CI config into a program that expects JSON. Comments are dropped, anchors are resolved, and everything runs locally in your browser. To go the other way, use the JSON to YAML tool, then validate the result with the JSON Validator.

How to Use

1Open YAML to JSON and paste or type your data into the input area.
2Adjust any available options to match the result you want.
3Your output is generated instantly — no button-clicking required for most tools.
4Use the Copy or Download button to save your result.

Common Use Cases

Debugging API responses while building web and mobile apps
Cleaning up minified or messy JSON from logs and network tabs
Preparing configuration files and fixtures for testing
Converting data between JSON and other formats for imports/exports

Frequently Asked Questions

What happens to comments in my YAML?

JSON has no concept of comments, so any YAML comments are omitted from the output. All the actual data — keys, values, lists, and nested maps — is fully preserved.

Are YAML anchors and aliases supported?

Yes. Anchors and aliases are resolved during parsing, so the JSON output contains the fully expanded values rather than the reference syntax.

Is YAML to JSON free to use?

Yes. YAML to JSON is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use YAML to JSON?

Absolutely. YAML to JSON runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
