YAML ↔ TOML Converter

Convert between YAML and TOML configuration formats with syntax validation and proper formatting

Examples:

About YAML and TOML

  • • YAML (YAML Ain't Markup Language) emphasizes human readability with indentation-based structure
  • • TOML (Tom's Obvious, Minimal Language) is designed for clear configuration files
  • • Both formats are popular for configuration files
  • • YAML uses indentation and colons, TOML uses equals signs and brackets
  • • Both support comments, strings, numbers, booleans, arrays, and nested structures

Conversion Notes:

  • • Comments are not preserved during conversion
  • • YAML anchors and references are resolved before conversion
  • • Date/time handling may vary between formats
  • • Some complex YAML features may not have direct TOML equivalents
  • • Array of tables in TOML becomes array of objects in YAML

Format Comparison:

YAML

  • key: value
  • nested:
  •   child: value
  • list:
  •   - item1
  •   - item2

TOML

  • key = "value"
  • [nested]
  • child = "value"
  • list = ["item1", "item2"]
  • [[array_of_tables]]
  • name = "entry"
