JSON to YAML

Bidirectional conversion between JSON and YAML, commonly used in configuration file scenarios.

Conversion Direction

Usage

JSON vs YAML

  • JSONJSON uses curly braces and square brackets to represent structure, strict syntax, requires quotes around keys and string values.
  • YAMLYAML uses indentation to represent hierarchy, more human-readable, supports comments, widely used in configuration files (Docker Compose, Kubernetes, CI/CD, etc.).

YAML Syntax Essentials

  • Use space indentation to represent hierarchy (no tabs allowed)
  • Key-value pairs separated by :, space required after colon
  • Array items start with -
  • Strings usually don't need quotes; use quotes when containing special characters
  • Supports # comments

Bidirectional Conversion

Supports both JSON → YAML and YAML → JSON bidirectional conversion. Switching direction automatically swaps input and output content. The YAML parser is a simple implementation supporting common key-value pairs, arrays, nested objects, and multi-line strings.
