YAML to JSON Converter – Free Online Tool
Parse YAML and convert it into valid JSON instantly. Our free YAML to JSON Converter supports multi-line strings, anchors, and complex YAML structures for seamless transformation.
About YAML to JSON Converter
YAML configuration files are popular for their readability, but many tools require JSON format. Manually converting YAML indentation and syntax to JSON brackets and quotes is error-prone. This YAML to JSON converter parses YAML and outputs valid JSON instantly.
How it works
Paste your YAML into the Input area. Choose 2 or 4 spaces for JSON indentation. Click Convert to JSON and the tool parses the YAML structure, converting lists, mappings, and scalar values into equivalent JSON format.
The converter handles nested structures, boolean values, numbers, and strings. Sample YAML demonstrates typical configuration with users array, metadata object, and nested settings. Copy or Download saves the JSON output.
When you'd use this
DevOps teams working with Kubernetes or Docker configs often need JSON for tools that do not accept YAML. Developers migrating from YAML-based configuration to JSON-based systems benefit from quick conversion.
This converter handles standard YAML features. Advanced YAML like anchors, aliases, and multi-line strings may not convert perfectly. For complex YAML files, verify the output matches your expectations.
Questions
Does it handle nested YAML?
Yes. Nested mappings and lists are converted to nested JSON objects and arrays.
What about YAML anchors?
Anchors and aliases are not fully supported. The converter processes the basic structure only.
Are comments preserved?
No. JSON does not support comments, so YAML comments are removed during conversion.
Can I convert JSON back to YAML?
This tool only converts YAML to JSON. Use a separate JSON to YAML converter for reverse conversion.
Is my data sent anywhere?
No. All conversion happens in your browser. Your YAML content stays private.
