YAML Formatter and YAML to JSON

Convert common YAML config structures to JSON and JSON back to YAML. This lightweight parser supports simple objects, arrays, strings, numbers, booleans, and null values.

YAML notes

What is YAML?

YAML is a human-readable data serialization format commonly used for configuration files, CI pipelines, Kubernetes manifests, and infrastructure tooling.

How does the YAML tool work?

This lightweight formatter parses common YAML key-value structures and arrays, then converts them to JSON. It can also serialize JSON objects back into readable YAML-like output.

When should you use YAML?

  • Inspecting small YAML configuration snippets
  • Converting simple YAML into JSON for tools and tests
  • Preparing JSON data as readable configuration examples
  • Debugging indentation and scalar values in config files

What are the limitations of YAML?

  • Advanced YAML features such as anchors, aliases, tags, and multiline blocks are not fully supported
  • This tool is intended for simple structured snippets, not full YAML specification validation
  • Comments are ignored during conversion

YAML examples

yaml name: AdminForge -> { "name": "AdminForge" }
array tools: - json - jwt -> { "tools": ["json", "jwt"] }
json {"private":true} -> private: true
