YAML to JSON Converter

YAML to JSON conversion transforms YAML (YAML Ain’t Markup Language) data into JSON (JavaScript Object Notation) format. This is useful when you need to programmatically process configuration files written in YAML.

This tool features:

• Custom indentation — Choose between 2 or 4 spaces for the JSON output.
• Error reporting — Detailed syntax errors with line and column numbers.
• Preserves data types — Strings, numbers, booleans, arrays, and nested objects are all handled correctly.
• Full YAML 1.1 support — Powered by js-yaml library.

1. Paste your YAML — Copy and paste any valid YAML data into the input textarea. You can also click Load Example to load sample data.
2. Choose indentation — Select 2 or 4 spaces for the output JSON formatting.
3. Convert — Click Convert to JSON to generate the JSON output.
4. Copy or download — Use the copy button on the output area or click Download .json to save the result as a file.
