YAMLTools.DEV
A comprehensive suite of tools for working with YAML files. Visualize, validate, and convert your YAML data with ease.
What is YAML?
YAML (YAML Ain't Markup Language™) is a human-friendly data serialization language that can be used with any programming language. Its design prioritizes readability and simplicity, making it ideal for configuration files and data structures.
The current specification is YAML 1.2 (Revision 1.2.2, Oct 2021), which is widely supported by numerous frameworks and tools in virtually all popular programming languages, including JavaScript, Python, Java, Go, Ruby, and many more.
Its widespread adoption in modern technologies like Kubernetes, Docker Compose, GitHub Actions, and CI/CD systems demonstrates its versatility and effectiveness in representing structured data in a clear and maintainable way.

Our Powerful YAML Tools
Visualizer
Transform YAML into interactive visual diagrams. Explore your architecture with 8 diagram types, zoom, search, and dependency analysis.
- 8 diagram types: tree, flow, dependency, sequence, state, class, block, and interactive
- Dynamic zoom, drag & drop, smart filters, and real-time search
- Export as HD images and generate structural analysis reports
Syntax Checker
Validate your YAML in real time with detailed error messages, line numbers, and smart suggestions to fix mistakes before deployment.
- Real-time error detection with precise line highlighting
- Detailed error messages with line numbers and context
- Smart suggestions to fix common indentation and syntax issues
Converter
Convert between YAML, JSON, XML, TOML, TOON, and 5 more formats instantly. Bidirectional conversion with auto-detection and TOON for LLMs.
- Bidirectional conversion between 10 formats including TOON
- Automatic format detection and one-click conversion
- TOON format reduces tokens by 30-60% for LLM usage
