YAML to TOML Converter Serialization & AST Mapping Specification

Formula representation used for accurate calculations:

Native JavaScript AST = Parser.load(Input Source Stream) Target Output = Serializer.dump(AST, { indent, sortKeys, dialect })

Calculation Example: Strict Type Preservations: YAML & TOML Maps ↔ JSON Objects | Sequences ↔ JSON Arrays | Timestamps ↔ ISO-8601 Strings | Nulls ↔ null

Structured Data Types Mapping Matrix

Quick reference lookup table for standard unit calculations.

Standard type equivalencies across JSON, YAML, and TOML serialization formats.
Data Type / Construct	JSON Representation	YAML / TOML Representation
Key-Value Map	{ "key": "value" }	key: value / key = "value"
Array / List	[1, 2, 3]	- 1\n- 2 / [1, 2, 3]
Boolean	true / false	true / false
Null / Nil	null	null / ~ (omitted in TOML)
Multiline String	"Line 1\nLine 2"	\| (Literal) / """ (Multiline)
Numbers / Floats	42 / 3.14159	42 / 3.14159
