swap_horiz

Bi-Directional

JSON ↔ YAML Engine

Translates JSON manifests into YAML 1.2 with custom indentation (2 or 4 spaces), Flow style inline objects, and folded block scalar strings (> / |).

Default: 2-Space Indent

table_rows

TOML v1.0.0

JSON to TOML Config

Generates idiomatic Rust and Python package definitions with distinct handling for root tables, inline dictionary tables, and array of tables ([[servers]]).

Cargo & Poetry Ready

integration_instructions

TS 5.x Schema

JSON to TS Interface

Infers strongly typed interfaces, union primitives, optional properties for sparse fields, and generates camelCase keys while preserving source types.

Recursive Nested Types

code

SOAP / WSDL / RSS

XML to JSON Parser

Disentangles complex XML trees. Configurable attribute prefixes (@attr vs child node maps) and CDATA text content unpacking.

DOMParser Native Engine

dataset

Tabular Stream

CSV ↔ JSON / YAML Array

Auto-detects delimiters (comma, semicolon, tab, pipe), casts numeric/boolean literals dynamically, and handles multiline quoted values with zero memory churn.

Header Detection RFC 4180

Add-on

Semantic Schema Diff

Compare keys and structure across formats. Detect dropped keys, mismatched types, and schema regressions before pushing config manifests to production.

warning SPECIFICATION EDGE CASE

The ‘Norway Problem’ & YAML 1.2 Gotchas

Under older YAML 1.1 specifications, unquoted two-letter ISO country codes like NO (Norway) evaluate as boolean false, corrupting localization lists, deployment region variables, and database seed vectors.

check_circle How ToolAcre Protects Your Pipeline

Our WebAssembly YAML core defaults strictly to the modernized YAML 1.2 Core Schema. Only literal true and false are coerced into booleans, keeping country codes (NO, YES, ON, OFF) safely preserved as strings.

Comparative Parsing Behavior: YAML 1.1 vs YAML 1.2 AST Engine Comparison

Legacy YAML 1.1 (Danger) close

countries:

  - GB
  - NO   # Evaluates to: false!
  - SE

ports:

ToolAcre YAML 1.2 Engine done_all

countries:
  - "US"

  - "NO"   # Safe UTF-8 String
  - "SE"

ports:
  http: 0o755 # Explicit Octal Prefix

info Numeric prefixes: Numbers with leading zeroes in JSON trigger syntax errors; in TOML, octals mandate explicit 0o prefixes.

Zero-Egress Architecture for Proprietary Cloud Configs

Engineering teams routinely transform Kubernetes manifests (k8s.yaml), AWS IAM role policies, GitHub Actions workflows, and Docker Compose files. Sending these configurations through public web endpoints exposes internal service topologies, secret environment keys, and database network endpoints.
