What are JSON and YAML?

JSON (JavaScript Object Notation) and YAML (YAML Ain't Markup Language) are both human-readable data serialization formats used to store and exchange structured data. JSON uses a syntax based on JavaScript with curly braces and square brackets, while YAML uses indentation and a more minimal syntax. Both formats are widely used for configuration files, API responses, and data interchange between systems, with JSON being more compact and YAML being more readable for complex configurations.

Tool description

This tool converts data between JSON and YAML formats bidirectionally. It parses valid JSON and transforms it into YAML syntax, or takes YAML input and converts it to properly formatted JSON. The converter handles nested structures, arrays, objects, and all standard data types supported by both formats.

Features

  • Bidirectional conversion between JSON and YAML formats
  • Automatic formatting with proper indentation
  • Support for nested objects and arrays
  • Preserves data types during conversion
  • Error handling for invalid input

Use cases

  • Converting API configuration files between JSON and YAML
  • Transforming Docker Compose or Kubernetes configs to JSON
  • Converting JSON API responses to readable YAML format
  • Migrating configuration files between different tools
  • Converting YAML documentation examples to JSON format
