Your data stays private
All conversion happens locally in your browser. Your YAML data is never uploaded to any server.
How to Use the YAML to JSON Converter
Input Your YAML Configuration
Paste your YAML content into the text area, or upload a .yaml or .yml file. The converter supports all YAML 1.2 features including nested structures, arrays, and anchors.
Choose Output Formatting
Select your preferred JSON indentation: minified for compact output, or 2/4 spaces for human-readable formatting. Comments in YAML are automatically removed since JSON does not support them.
Convert to JSON
Click "Convert to JSON" to transform your YAML configuration. The conversion preserves all data types and structures while producing valid, well-formatted JSON.
Download or Copy JSON
Copy the JSON output to your clipboard or download it as a .json file. Use the converted data in APIs, JavaScript applications, or any system requiring JSON format.
Pro tip: Your data is processed entirely in your browser. Nothing is sent to any server, ensuring complete privacy.
How to Convert YAML to JSON
YAML and JSON are both popular data serialization formats, but they serve different purposes. YAML is more human-readable and often used for configuration files, while JSON is the standard for data interchange in web applications. Our converter makes it easy to transform between these formats.
Step-by-Step Guide
- Paste your YAML data or upload a .yaml/.yml file
- Select your preferred JSON indentation (minified, 2 spaces, or 4 spaces)
- Click "Convert to JSON" to process your data
- Copy the result or download as a .json file
YAML vs JSON
- YAML: Human-friendly, supports comments, uses indentation, often used for configs
- JSON: Machine-friendly, no comments, uses braces/brackets, standard for APIs
Common Use Cases
- Convert Docker Compose files for API consumption
- Transform Kubernetes manifests to JSON
- Convert CI/CD pipeline configs (GitHub Actions, GitLab CI)
- Migrate Ansible playbooks to JSON format
- Process configuration files in JavaScript applications
Frequently Asked Questions
What YAML features are supported?
The converter supports all standard YAML 1.2 features including nested objects, arrays, multiline strings, anchors, aliases, and comments (comments are stripped in JSON output).
Why convert YAML to JSON?
JSON is more widely supported by APIs, databases, and programming languages. Converting YAML configuration files to JSON makes them compatible with more tools and systems.
Are YAML comments preserved?
No, JSON does not support comments, so YAML comments are removed during conversion. The data structure and values are fully preserved.
How are YAML special types handled?
YAML-specific types like timestamps, binary data, and custom tags are converted to their closest JSON equivalents (strings, base64 strings, etc.).
Can it handle multi-document YAML?
Currently, the converter processes the first document in multi-document YAML files. For multiple documents, convert them separately or merge them first.
