YAML to JSON Converter
Parse and convert YAML 1.2 configuration documents into structured, formatted, or minified JSON objects and arrays.
Quick Answer & Understanding Your Result
A YAML to JSON Converter transforms YAML 1.2 configuration documents, Kubernetes specs, and Docker files into structured, valid JSON objects.
Core Parsing Capabilities (YAML 1.2)
- Whitespace & Indentation Parsing: Resolves 2-space and multi-level indentation blocks into nested JSON object hierarchies.
- Native Datatype Resolution: Correctly converts YAML scalars, booleans (
true/false,yes/no), integers, floats, and nulls (~) into standard JSON types. - Multi-Document Support: Parses multi-stream YAML files separated by triple dashes (
---) into sequential JSON arrays.
Cloud & API Ingestion Uses
- Kubernetes Spec Processing: Converting YAML deployment files into JSON for processing in programmatic CI/CD pipelines.
- Configuration API Consumption: Parsing YAML configuration files in microservices that natively consume JSON.
Paste your YAML code above to convert it into clean formatted JSON format instantly.
Formula & Calculation Logic
Technical Specification & ASTYAML AST parsing:
- Parses YAML lexical stream and serializes resulting JavaScript object tree into formatted JSON.
