YAML to JSON Converter
Convert YAML configuration files to JSON format.
About YAML to JSON Converter
Paste any YAML document and convert it to pretty-printed JSON. Handles nested mappings, sequences, multi-line strings, and basic YAML types. Useful for converting Kubernetes configs, GitHub Actions, or any YAML-based configuration to JSON for processing.
Use Cases
Converting Kubernetes YAML configs to JSON for API calls, transforming GitHub Actions to JSON for analysis, reading YAML config files in JSON-consuming tools, debugging YAML structure.
How It Works
Uses a client-side YAML parser (js-yaml loaded from CDN) to parse the YAML document into a JavaScript object, then JSON.stringify() to produce formatted JSON output.
Frequently Asked Questions
Does it support multi-document YAML?
Currently only single-document YAML (no --- separator between documents). Multi-document support is planned.
Are YAML comments preserved?
No. Comments are stripped during parsing. JSON has no comment support.
