}About This Tool
Convert YAML (YAML Ain't Markup Language) configuration files to JSON format. This tool parses YAML's human-friendly syntax - including indentation-based nesting, comments, and multi-line strings - and produces equivalent JSON for use with APIs, tools, or systems requiring JSON input.
Common Use Cases
- Converting Kubernetes YAML to JSON for kubectl
- Transforming Docker Compose files to JSON
- Processing CI/CD configs in JSON-based tools
- Converting YAML configs for JavaScript applications
- Validating YAML by converting to strict JSON
How to Use
- Paste your YAML content
- The tool parses YAML structure
- Comments are removed, structure is preserved
- Copy the equivalent JSON output
Features
- Parses YAML indentation and structure
- Handles YAML-specific features (anchors, aliases)
- Removes comments (not valid in JSON)
- Produces valid, formatted JSON
Tips
YAML comments are removed in JSON output since JSON doesn't support comments. Save your original YAML if you need to preserve comments.
