YAML to JSON Converter Online - Bidirectional
Convert between YAML and JSON formats. Perfect for Kubernetes manifests, Docker Compose, GitHub Actions, and DevOps workflows
About This YAML to JSON Converter
Tool for YAML to JSON conversion. This tool is part of the AI JSON Tools collection, providing specialized functionality for developers working with configuration files and data serialization. All processing happens entirely in your browser—your data never leaves your device.
How It Works
This tool uses the robust js-yaml library to parse YAML input and convert it to valid JSON. The conversion is bidirectional—you can also paste JSON and convert it back to clean, well-formatted YAML. All processing happens locally in your browser.
Common Use Cases
Developers use this tool for: 1) Converting Kubernetes manifests to JSON for programmatic processing, 2) Transforming Docker Compose files for CI/CD pipelines, 3) Converting GitHub Actions workflows to JSON, 4) Debugging YAML configuration files, 5) Integrating YAML-based configs with JSON-based systems.
Technical Details
The converter is built with vanilla JavaScript and the js-yaml 4.1.0 library loaded via CDN. It handles complex YAML features including anchors, aliases, multi-line strings, and nested structures. The implementation focuses on accuracy, performance, and ease of use.
Privacy & Security Guarantee
No data leaves your browser. All YAML to JSON conversion happens locally using JavaScript. This means you can safely work with sensitive information like API keys, authentication tokens, customer data, and proprietary configurations. There is no server-side processing.

What versions of YAML are supported?
The converter uses js-yaml 4.1.0 which supports YAML 1.2 specification. It handles anchors, aliases, multi-document YAML, and complex nested structures.
Are YAML comments preserved?
Comments are lost when converting YAML to JSON since JSON does not support comments. If you need to preserve comments, keep your original YAML file.
Can I convert multi-document YAML?
Yes. Multi-document YAML (separated by ---) is converted to an array of JSON objects, one per document.
How are YAML anchors and aliases handled?
YAML anchors (&anchor) and aliases (*anchor) are fully resolved during conversion. The resulting JSON contains the expanded values.
