About This Tool
Parse YAML into a JSON object using Python's safe_load for security. Supports all standard YAML constructs: mappings, sequences, scalars, multi-line strings, and anchors.
Only safe YAML types are accepted — no arbitrary Python objects or custom tags. This prevents code execution via malicious YAML.
Why Use This Tool
- Config Parsing — Parse YAML configuration files (Kubernetes manifests, CI/CD pipelines) into JSON for programmatic access.
- Data Import — Convert YAML data files into JSON for ingestion into databases or APIs.
Frequently Asked Questions
Is it safe to parse untrusted YAML?
Yes — we use safe_load which only accepts standard YAML types (strings, numbers, booleans, lists, dicts). No arbitrary object instantiation.
Are YAML anchors supported?
Yes — anchors and aliases are resolved during parsing and the final JSON contains the expanded values.
