JSON to TOML Mapping

Converting JSON to TOML is straightforward but has some specific rules:

  • Objects: Nested JSON objects become [tables] or [[array of tables]] in TOML.
  • Arrays: JSON arrays map to TOML arrays. If they contain objects, they become array of tables.
  • Primitives: Strings, numbers, and booleans map directly.

Benefits of TOML

Why prefer TOML over JSON for configuration?

  • Ease of Use: TOML is significantly easier for humans to write and edit manually.
  • Comments: TOML supports inline and block comments (#), making it self-documenting.
  • Visual Clarity: The table-based structure avoids the "deep nesting" visual clutter often found in large JSON files.
