Bidirectional JSON and YAML Conversion Tool
Convert between JSON and YAML formats with flexible options:
Convert JSON configuration files to YAML format for Kubernetes manifests, Docker Compose files, and container orchestration configs. YAML's readability makes it ideal for DevOps workflows.
Transform configuration files between JSON and YAML for CI/CD tools like GitHub Actions, GitLab CI, CircleCI, and Jenkins. Many modern CI/CD platforms prefer YAML for pipeline definitions.
Convert application config files between formats. Many frameworks support both JSON and YAML, allowing you to choose the most readable or convenient format for your development environment.
Convert data structures from JSON format to YAML for Ansible playbooks, roles, and inventory files. Ansible exclusively uses YAML for its configuration and automation scripts.
Transform API specifications between JSON and YAML formats. OpenAPI supports both, and YAML is often preferred for its readability and support for comments in API documentation.
Convert data between JSON and YAML for different storage or transmission needs. Use JSON for APIs and web services, YAML for human-readable config files and documentation.
JSON and YAML are two popular data serialization formats, each optimized for different use cases and workflows.
JSON (JavaScript Object Notation) is a lightweight, text-based data format that uses human-readable text to store and transmit data objects. It supports hierarchical structures with nested objects and arrays, making it ideal for web APIs, configuration files, and data exchange. JSON is language-independent and has become the de facto standard for web services.
YAML (YAML Ain't Markup Language) is a human-friendly data serialization format designed for configuration files and data exchange. YAML offers advanced features like anchors and aliases for reusing data blocks, support for comments, multi-line strings without escaping, and minimal syntax without brackets or quotes. It's significantly more readable than JSON for complex configurations, making it popular in DevOps, CI/CD, and infrastructure-as-code tools.
Select 'YAML to JSON' mode, paste your YAML data, choose your preferred JSON format (pretty or minified), then click Convert. The tool will automatically transform your YAML into valid JSON format, preserving data structure and values.
Select 'JSON to YAML' mode, paste your JSON data, choose your preferred indentation (2 or 4 spaces), then click Convert. The tool will generate clean, properly indented YAML that follows best practices for readability.
When converting YAML to JSON, anchors and aliases are automatically resolved and expanded into their full values. JSON doesn't support reference syntax, so all referenced data is duplicated in the output. Converting JSON to YAML creates standard YAML without anchors.
The converter is designed for single-document YAML files. If your YAML contains multiple documents (separated by '---'), you'll need to convert each document separately. Split your multi-document YAML before conversion.
This is a formatting preference. 2-space indentation is more compact and commonly used in YAML files for configuration. 4-space indentation provides better visual hierarchy and is often preferred for complex nested structures. Both are valid YAML.
YAML supports comments (lines starting with #), but JSON does not. When converting YAML to JSON, all comments are removed because JSON has no comment syntax. When converting JSON to YAML, no comments are added to the output.
The converter uses UTF-8 encoding, which supports all international characters including special symbols, emoji, and non-Latin scripts. Both JSON and YAML use UTF-8, ensuring full compatibility with global content.
Yes, absolutely. All conversion happens entirely in your browser using JavaScript. Your data is never uploaded to any server or transmitted over the network. This ensures complete privacy and security for sensitive configuration files.
