YAML to JSON Converter
Convert YAML to JSON using a real YAML parser - handles nested mappings, sequences, and scalar types correctly.
Paste YAML below - this tool parses it with a real YAML parser and outputs clean, formatted JSON.
For the reverse direction, see the JSON to YAML Converter.
How to Use It
- Paste valid YAML.
- Click Convert.
- Copy or download the resulting JSON.
Understanding the Result
YAML mappings become JSON objects, sequences become arrays, and scalar types (strings, numbers, booleans, null) are preserved according to YAML's own type inference rules.
Common Errors
YAML is indentation-sensitive - a common source of parse errors is mixing tabs and spaces, or inconsistent indentation between sibling keys. This tool reports the parser's error message to help pinpoint the issue.
